You had your fair share of less than graceful moments but based on the amount of times you nearly fell to the floor reaching for the lab phone, this was becoming a habit instead of just happenstance. Even so, you braced yourself on the countertop and pulled the phone to your ear, greeting whoever was on the other line with your honorific.
“Hey, it’s me,” Spencer greeted you, his voice low and quiet on the other line, but hearing him shocked you, nonetheless. Usually, if he was off on a case, you would only hear from him first thing in the morning or last thing before bed.
Despite knowing he probably needed help with a chemistry-related murder, his voice was a welcome sound in the quiet of your research lab. “Hi, me,” you teased, turning back to your computer monitor to continue your grant application. “How’s California?”
He hummed through the phone, “It’s alright. What have you heard?”
Faltering for a moment, your smile dropped at the implication. “You know I don’t pay attention to the news while you’re gone.” It only made you worry, and he’d fill you in on all of the important stuff when he came home.
“I know,” he assured you. “I just wanted to make sure no one had said anything. You didn’t answer your cell phone when I called.” He sounded nervous but didn’t clue you in to what was fueling his anxiety.
A quick glance around the lab told you that you’d left it in your office this morning, because you remembered having it in the car on your way to work. “I’m in the lab,” you told him, knowing he’d probably called your lab phone with a slightly elevated heart rate—concern that was only ever reserved for you.
Someone cleared their throat on the other line, and you realized Spencer wasn’t alone. “Are you busy?”
“Not too busy for the BAU,” you told him, knowing that was the only reason he’d have you on speakerphone during an active case.
Eventually, someone else spoke up. “Hey, girl genius,” Derek said in his usual smooth tone. “How high would a university faculty member need to rank in order to have access to sarin?”
Your mouth went dry. Tamping down your imagination before it ran entirely wild, you tried to maintain your focus. “Strictly speaking? Not very high. Sarin’s an organophosphorus compound and an irreversible inhibitor of acetylcholinesterase-“
“Hey, English for us common folk, please,” Rossi interrupted, stopping you from going off on a tangent in what might as well be an entirely different language.
An unfamiliar voice spoke next, “How on earth did you find two of them?”
Cheeks burning, you heard JJ explain that you were Spencer’s fiancé before you continued speaking. “It’s a compound. Made up of phosphorus, fluorine, a methyl group, and an isopropoxy group, all of which are relatively accessible in most labs. It’s not about what’s in it, it’s the compounding of each component that turns it into sarin.”
“So, it’s not difficult to make?” Hotch asked you over the phone, his tone verging on frustration that you were rarely privy to. Spencer tried his best to keep his work away from you, exactly how you wanted it.
You sighed, “No, it’s not. The difficulty comes in transport and storage. Usually, it’s kept as what’s called a binary weapon, meaning it’s kept in two parts that, when combined, make sarin. We don’t keep it in the lab, but I’ve made it before.”
“Do any labs keep it around?” The stranger’s voice asked.
Racking your brain for anything you’d heard through the rumor mill, you shrugged. “Military labs, probably,” you said. “It’s highly regulated; you have to go through all kinds of paperwork to use it for research purposes. If you don’t have the proper approvals, you’re probably committing a war crime.”
The guy cleared his throat, “Is there another person we could ask?”
“No,” Spencer answered for you. “If you’re looking for an expert in chemical warfare, she’s the best in her field.”
You smiled softly at the compliment, “I’m also not someone you have to worry about blabbing to the media.”
“She’s our favorite consultant for all things chemistry related,” Derek said, and you imagined him winking at Spencer, tormenting him.
Humming, the rest of the team said goodbye to you, and you were just left with Spencer. “Am I still on speaker?”
There was a shuffling on the other side before you heard his voice again, “Not anymore. Are you okay?”
You knew he was specifically thinking of another time he’d asked for your help with a case. It’d thrown you into such a funk that the two of you made a deal. You were only available to help with problems that were strictly chemistry-related, and Spencer would only tell you surface-level case information. “Yeah,” you whispered, throat dry. “Spence, you’re being careful, right?” You looked down at your left hand, engagement ring sparkling under the fluorescent light of the lab.
Spencer sighed, trying to think of an answer that would comfort you, “Have I ever not come home to you?”
Laughing humorlessly, you rolled your eyes. “Is that really the yardstick you want to be using?” In the five years you’ve been together, there have been many injuries, the worst of which was a bullet to the neck. Not to mention the shot to the knee and anthrax poisoning that you’d been told about after the fact—on your third date.
“We’re being safe, my love,” he told you, keeping his voice down to avoid being teased for his affection toward you.
You tried to take a deep breath, but there was still a pit in your chest. “And the reason you called me for help with a question you already knew the answer to…?”
He hummed in amusement, knowing he’d been caught. “I miss you,” his voice was gentle, so much so that you wondered how such a gentle person could do such a horrific job. Though you supposed that’s part of why you worked so well together.
“I miss you too,” you whispered, though there were no prying eyes around you. “I love you,” you added for good measure.
“I love you too,” he responded in kind. “I have to go, stay away from the news, okay, baby?”
His tone didn’t exactly instill confidence in you, but still, you replied, “Yeah, promise.” And after a hesitant beat, the call ended.

A/N: Hi! 🤭💖
The dimly lit room was filled with the smell of chemicals, the faint hum of a nearby reactor providing the only sound beyond the rhythmic tapping of your gloves against the lab counter. The clink of glass was interrupted by the sound of the door swinging open.
"Ah, the ever-diligent chemist. How fitting," Aventurine's voice echoed in the space, his usual charismatic lilt evident even from across the room. His eyes, vibrant against the cool lab setting, locked onto you. "Though, I must admit, it’s quite the surprise to see you working away in a place so… grounded. I expected a more, shall we say, high-stakes environment?"
You glanced up from your work, momentarily distracted by his entrance, his ever-present aura of elegance and flamboyance. His attire shimmered slightly as he stepped closer, a confident grin spreading across his face. His earring swayed lightly, a reflection of his calculated risk-taking nature.
"You know," he continued, eyes scanning the rows of equipment and flasks, "it’s fascinating to think of all these reactions taking place under controlled conditions. The precision, the balance... It's all a gamble, isn’t it?"
You offered a smile, adjusting your goggles and continuing your work. "Science is about precision, Aventurine. The risks are calculated, not blind."
He chuckled, the sound light yet tinged with something darker. "Calculated, yes. But the stakes? Higher than most realize. Just like in a game of chance."
His eyes briefly flicked over the various chemicals you were working with. "Tell me, do you ever feel the thrill of the unknown? Or are you simply too focused on outcomes?"
His gaze never wavered, his tone teasing but sincere. You could feel the weight of his questions, the underlying need to probe not just your work but the person behind it.
"I think you know the answer to that," you replied, locking eyes with him. "Everything’s a gamble, just like you say. But it’s the right mixture that matters."
Aventurine smirked, a dangerous gleam in his eyes. "Perhaps we could test that theory sometime... but not today." He turned, the air around him shifting like a gust of wind. "One day, we’ll see what happens when risk meets the unmeasurable. Until then, I’ll leave you to your work. Just remember, my dear chemist... every choice you make is a bet."
The faint glow of the celestial halo behind his head illuminated the room with a soft, ethereal light. Sunday’s tailcoat swayed gently as he approached, his gaze distant yet kind. His eyes, tinged with sorrow, focused on you as you mixed chemicals in the corner of the lab, your hands steady and deliberate.
"Another attempt at perfection, I see," Sunday’s voice was calm, like the peaceful winds of a faraway land, his wings fluttering slightly behind his ears, the golden studs catching the light as he spoke. His tone was both reflective and filled with a quiet yearning. "In this world, we seek balance. Yet, how often does it elude us? It’s a constant search, isn’t it?"
You met his gaze, your own work momentarily forgotten as you studied him. His quiet demeanor, the way he carried both pain and hope within him, drew your attention. You couldn't help but wonder if he saw the same pursuit of balance in your craft, or if he saw something deeper in the chemicals and reactions you worked with.
"It’s about finding harmony, Sunday," you answered, voice soft as you measured out the final ingredients for your current project. "In science, we learn to balance elements, reactions, and outcomes. Maybe that’s the same as seeking peace in life."
He stepped closer, his gaze shifting to the instruments you used, his eyes lighting up with recognition of your process. "Is it the balance that you seek? Or the absence of pain?" His voice was laced with sadness, but also a touch of curiosity, as if he were searching for something even within himself.
You thought carefully before responding. "Perhaps both. We want to understand, control, and find peace in the chaos. Just like you, I think."
Sunday smiled faintly, his wings fluttering softly as he took a step back. "And perhaps… that’s why we both struggle. Harmony is not the absence of chaos—it’s the acceptance of it. Even in the most beautiful of creations, there is disorder. Yet we press on, hoping that one day, the vision will come clear."
His halo shimmered slightly, an almost imperceptible glow flickering around him. "May you find your balance, chemist. I will continue searching for mine."
Ratio strode into the lab with the confidence of someone who had already solved a thousand problems. His violet hair bounced with each step, the glow of his eyes calculating and sharp as he approached your workspace. He leaned against the counter with an air of nonchalance, his arms folded across his chest.
"You’ve been at this for quite a while, haven’t you?" His voice was deep, and his eyes flickered over your work with sharp attention. "The pursuit of knowledge is both taxing and exhilarating, is it not?"
You glanced up from your microscope, meeting his intense gaze. There was something about the way he spoke that suggested both admiration and an almost dismissive curiosity. Ratio was a man who didn’t bother hiding his superiority, yet there was an underlying respect for those who shared his passion for intellect.
"Knowledge is everything," you answered, setting your work down and meeting his eyes. "But it also requires patience, something you might not understand."
Ratio let out a low chuckle, his smile confident and knowing. "Oh, I understand patience quite well. It’s the subtle application of time to maximize results. However, the art of true knowledge lies in mastering not only the facts but the means to spread them. To eradicate ignorance, one must wield it like a weapon."
He moved closer, his hand brushing over a nearby set of vials. "Tell me, chemist, how do you feel when you uncover something new? A breakthrough in your work, a new compound or discovery?"
"I feel… accomplished," you replied, your fingers brushing the edge of your tools. "But it’s always followed by more questions. Science never ends."
Ratio’s eyes glittered. "Yes, exactly. That’s what makes it so fascinating." His voice dropped into a low murmur, like the whisper of knowledge itself. "But unlike you, I don’t believe in endless questions. I believe in the answers—those that are tangible, those that can be spread far and wide to shape minds."
He studied you for a moment, as if considering your worth as a partner in his pursuit. "Perhaps you could help me answer a few questions. Or would you rather stay trapped in the pursuit of the unknown, forever circling, like so many others?"
There was a challenge in his words, yet something unspoken lingered behind his confident demeanor. His belief in his own superiority was clear, but so was his admiration for those who dared to challenge his intellect.
"Would you like to test your theory?" you asked, a sly smile tugging at your lips.
Ratio’s eyes gleamed with approval. "I thought you might say that."

“Time?” You asked, using the heel of your shoe to slam the door shut once you made your way through. Haphazardly, you dropped your backpack on the ground in front of the coat closet before rushing toward the bedroom.
Spencer was sitting on the couch, a glass of water on the side table and a book in his lap, he glanced over at you when you stopped at the back of the couch to say hi to him, “Forty minutes.” He reached out for your arm, a careful gesture just because he wasn’t ready for you to be out of his view yet, but his hand caught on your forearm.
You hissed at the contact, pulling your arm back and shaking it out, “Tight grip,” you tried to wave it off, but Spencer wasn’t easily convinced.
“I barely touched you,” he said, snapping his book closed and standing up, following you into the bedroom. “Let me see your arm,” he asked, opening the door when you tried to close it behind you.
Spinning on your heel, you shrugged at him, “Not without a warrant,” you told him. Your eyes burned as you begged yourself not to cry at the pain.
Your boyfriend reached out for you again, this time pulling you in by your belt loops, he herded you into the bathroom, holding onto your hips as he beckoned for you to sit on the countertop. The granite was cold even through your jeans, and Spencer took your discomfort as pain as he pulled your shirt off.
You grunted, frowning while he pulled your long sleeve over your head and dropped it in the laundry hamper, “It’s cold,” you grumbled, slouching as Spencer inspected the wound on your forearm. It looked a lot worse now than it had when you left the lab, the burned skin starting to develop a yellowish hue. “I have somewhere to be tonight, you know,” you reminded him.
This would be your second outing with the BAU ladies since you were first introduced to them a few months ago, Garcia had arranged tango lessons, and Emily was meant to be your dance partner. “What did you burn yourself with?” He holds your arm timidly, pinching your wrist between his index and his thumb and eyeing the burn with growing concern.
“Uh,” you hummed, bracing yourself for what is bound to be abject disappointment, “Nitric acid.”
Spencer set your arm down, resting it burnt side up on your thigh while he buried his face in his hands, “Baby,” he said from behind his palms.
When he said it in that tone, it was easily your least favorite nickname. “I didn’t think it was concentrated enough to burn,” you tried to defend yourself, looking down at the obvious mistake you had made. “It must have been mislabeled and no one caught it,” you told him, trying to shrug it off.
Dropping his hands, Spencer resorted to crossing his arms in front of his chest, “A lot of chemicals have been getting mislabeled lately.” It was an accusation, but not toward you, though you tended to be more lenient on lab safety than most of your colleagues.
“I…” You faltered, flexing your fingers and feeling the skin on your arm pull, “Yes, but—”
Spencer shook his head, “No, you have to talk to her.”
The her in question was your grad student, Leslie, who had made a similar mistake with hydrochloric acid last month, also leading to a chemical burn on your arm. You frowned at Spencer, making your expression as pleading as possible in hopes that he’d drop it.
“This can’t keep happening,” Spencer said, “I know you don’t want to make her feel guilty, but maybe she should. Maybe that’s how she learns.”
You furrowed your brows at him, “It wasn’t her fault.” You felt defensive over your lab assistant, knowing that she had asked you to be her thesis advisor made you feel the need to protect her.
He pressed his lips in a thin white line, “It was,” he corrected. “If you don’t say something, I’ll send an email to your boss.”
“Spencer,” you said, shoulders slumped in disappointment and the faint feeling of betrayal.
Raising his eyebrows, Spencer gingerly took your arm back in his hands, “I know that’s your thing around the lab, not wanting to cause trouble. You don’t want to draw attention to yourself, but I need you to take care of yourself, and you can’t do that if you keep being so flippant about these ‘accidents.’”
You knew what he was doing, turning it into something you could do for him instead of something you’d do for yourself. “I’ll talk to her on Monday, and I’ll redo the UV spectroscopy on the nitric acid,” you surrendered, giving yourself the weekend to figure out how to broach the topic.
He set your arm down again, opening the cabinets in the bathroom and shuffling through miscellaneous belongings. Between the two of you, you had quite a remarkable collection of first aid, the basket that Spencer pulled off the shelf was intimidating, “Here, hold your arm over the sink,” he instructed, guiding you gently so he could rinse the burn with saline. “Does that hurt?”
“it’s just cold,” you answered, watching him make sure any debris was flushed from the wound.
His head bobbed, setting down the saline container and moving to coat the wound with a panthenol cream, “Were you wearing your hazardous materials pin?”
Your face warmed at his question. The one time you’d been the root cause of a spill, your boss responded by gifting you an enamel pin with the hazardous materials pin, “I was.”
“Maybe it needs to be bigger,” he proposed, filtering through the bin of first aid supplies and hunting for something specific, reading the labels on everything before he put it on the burn.
The corner of your mouth quirked up when you noticed he was trying to lighten the mood, “Or have lights on it,” you offered, imagining a border of LEDs around the pin.
Spencer hummed, finding silver sulphadiazine to cover the wound with, “Now, there’s an idea.”
You laughed breathily, “I could get it tattooed,” you waggled your eyebrows at him. “It would make a nice tramp stamp,” you told him, watching his gentle fingers apply dressings to your wound, securing them as carefully as he can so your skin doesn’t get irritated.
“But then I’d be the only one to see it,” he countered playfully, inspecting his handiwork.
Conceding, you nodded, “Unless the people in the lab get comfortable with a lot of things really fast.”
Softly, Spencer leaned forward and kissed you, “I want to keep an eye on this tonight,” he whispered against your lips. “If it doesn’t get better by the morning I’m taking you to urgent care,” he told you, kissing you again before gathering the first aid wrappings and putting them in the trash can.
He stepped out for a moment, returning with an old Princeton t-shirt of yours. You gingerly pulled it over your head, making sure not to bump your fresh bandages as you did so, “But what about my dance lessons?”
You hopped off of the countertop to be met by Spencer standing right in front of you, his hands placed gently on your waist before he whispered, “I can teach you to tango perfectly fine in the living room.”

"Thanks for stopping so I could change,” you say to Spencer, leading the way into your apartment and locking the door behind you. “I’m sure lab dress code and David Rossi dress code are miles apart,” you continue, hanging your backpack on the wall.
Spencer hums in response, “You’d look great in anything you wear.”
Your face warms at the compliment, “You’re sweet. You can just wait out here, I shouldn’t be more than a couple of minutes,” you gesture to the living room, smiling at him before heading off to your room.
Nervously, you pull off your lab-safe attire and discard all of it into the laundry hamper before putting on the dress you’d chosen for dinner tonight. It’s not overly fancy, but you hope his team will like it. You hope his team will like you.
Looking at yourself in your dresser mirror, you reconsider your choice of shoes, switching from a pair of kitten heels to flats before walking out the door, “Hey, Spence, is Rossi’s patio heated, or should I bring a sweater for when the sun goes down?” You stop in your tracks when you find Spencer, still in the entryway, looking at the color-coded whiteboard calendar you keep by your front door, “What’s up?”
His hands are stuffed in the pockets of his slacks, and he looks upset. What’s worse is you think he might be upset with you. “What’s this dinner you have planned next Friday?”
You feel like a child who’s been caught doing something they shouldn’t be, draping the proposed sweater over the back of a kitchen stool and crossing your arms in front of your stomach. “It’s a work dinner,” you answer nervously.
“With?” Spencer asks, but he’s not pushy about it, there’s something desperate in his tone.
Pursing your lips, you look at the purple writing on the calendar, “The chair of Biochemistry and Molecular Genetics at Northwestern, and a representative from the college's dean. They’re offering me a job with a private lab and my own team of researchers… so they’re taking me out to dinner.”
Spencer’s face fell, “They’re offering you a job in Chicago?”
“Well, that’s where Northwestern is. Evanston, if you want to get technical about it,” you respond, chewing on the inside of your cheek.
He looks at you dumbfoundedly, “I don’t want to get technical about it. When were you going to tell me that you’re taking a job in Chicago?” It almost seems like he’s afraid.
You raise your eyebrows in curiosity, you’ve been seeing each other for a month, and you’ve never known Spencer to jump to conclusions. “I’m not,” you tell him, keeping your tone void of any accusation, “They’re just taking me to dinner.”
Spencer sighs, “But they’re offering you a job. In a different state. In a different timezone.”
Admittedly, he was beginning to sound a bit ridiculous to you, “Don’t you field offers from colleges all the time? They want you to teach or tell you to become Spencer Reid, PhD, PhD, PhD, PhD, or whatever?”
His eyes follow you as you move to sit down at the kitchen counter, “It never gets as far as dinner.”
“I’m not taking the job,” you tell him simply, shrugging your shoulders demurely.
Spencer falters at that, knitting his brows together as he tries to piece together the answers you’re willingly giving him, “If you’re not taking the job then why are you going to dinner with them?”
Hiding a small smile, you give him the truth, “They pick up the tab. I go to a lot of these and I get good food out of the deal. These people love to schmooze but I’ve never been offered anything that I would be inclined to accept.” This specific job seemed perfect on the surface, but they weren’t willing to let you choose what to research. That was non-negotiable for you.
“I could schmooze you,” he insists, “You don’t need other people to schmooze you.”
You giggle at him, waving him over to you so you can look him in the eyes when you tell him, “I go for free food and good wine. No other reason.” Your smile was gentle, but inside your heart was pounding. He was scared I was going to leave, you think to yourself.
He sighs, “Will you… will you tell me in the future when you get these dinner offers?” His voice is tentative, almost as if he’s afraid you’ll think he’s asking too much of you.
Nodding, you reach out and take one of his hands in yours, “I can, but I didn’t think were at the ‘I’m being courted by another workplace, and I wanted to let you know’ stage yet. That’s kind of a girlfriend thing,” you explain.
Spencer frowns, “Aren’t you?”
Tilting your head to the side, you look at him curiously, “Aren’t I what?”
“My girlfriend,” he clarifies.
Your eyes go wide, “Oh! I didn’t think so, I thought you had to ask yet.” Although you’re far from a relationship expert, you’d had to ask your PhD advisee what to wear before your first date with Spencer.
The panicked look on his face returns, “I’ve been telling people you’re my girlfriend. Should I not have been doing that?”
Shaking your head, you beam up at him, “I don’t mind. I just thought you had to ask about that kind of thing.”
“I don’t know,” he admits, “I’ve never really done this before.”
The two of you sit in an awkward silence for a moment before you decide to speak up again, “So, just so we’re on the same page. I’m not moving to Chicago.”
Spencer frowns again, and you have to hold yourself back from using your thumb to smooth out the crease on his forehead, “Will you?”
Confused, you lean your head back, “Move to Chicago?”
“Be my girlfriend,” he amends quickly.
You nod, “I would love to.”
“And just so we’re on the same page,” he ducks his head down, so close to a kiss that it makes you feel dizzy, “I like to think I’m the only one who can really court you.”
Laughing, you lean forward and peck his lips, “I would be insulted if you didn’t think that.”

“Do you have a second?” Spencer asks, his voice slightly choppy over the phone. Between his ancient phone and being inside concrete police precincts, some disconnect was bound to happen.
Saving your document to your computer, you rest the lab phone between your shoulder and ear, “If you’re asking me if I have any corrosive chemicals in my hands, the answer is no.”
He chuckles lightly, “I never know with you.”
You roll your eyes in response, even if he can’t see you, “It was one time and I needed a new phone case anyway.”
“You fused the plastic of your phone case to the material of your phone,” he retorts far too quickly for your liking.
“Yes,” you acquiesce, “but I know the exact chemical reaction that caused that phenomenon.” You cross your legs one over the other, maintaining your balance on your lab stool as you speak to Spencer over the phone.
He gave a light hum in response, “Speaking of chemical reactions – I need your help.”
Your eyebrows shot up in surprise, “You’re asking me for help in chemistry?” There really was a first time for everything, you suppose.
Spencer was more than capable of navigating a lab on his own, even so, he admits, “You have more applied practice than I do.”
Pursing your lips, you nod to yourself, “Fair enough. What’s stumping you, Dr. Reid?” Your inquiry, while innocent enough, garners a wolf whistle from your graduate assistant.
“There’s something burning a hole in these bones, and I’m not sure what would be causing it to happen this fast,” he explains, giving you minor background information on how long the bones were out and if the medical examiner had treated them with something.
You clear your throat, frowning at the notes you had scrawled down in front of you, “Burning or corroding?” What was seemingly a meaningless distinction would actually allow you to filter through approximately half of the possibilities.
“Corroding,” he corrects himself, “My mistake.”
Crossing off some of your notes, you purse your lips at the new possibilities, “No worries. Did you try flushing it out with water?”
You hear papers flipping on his end of the call before you get a response, “That would destroy evidence.”
“Well,” you raise your eyebrows, “It sounds like your evidence is destroying itself.”
“Baby,” Spencer says in a no-nonsense tone reserved for when he was deep in a case. You could’ve sworn you heard Morgan in the background of the call mocking him for the pet name.
Turning back to your notes, you sigh, “Yeah, yeah, all work and no play. Was the body buried?”
“Partially,” his reply intrigues you, “I can have Garcia send you the crime scene photos if you think it’ll help.”
Wrinkling your nose at the thought, you made an unsure sound, “Right, because nothing says lunchtime like getting up close and personal with a homicide victim.”
“What lunchtime? It’s three pm in D.C. right now,” he caught you, a slight chiding tone in his words.
Ignoring his questions, you ask more of your own, “Was the body near water? Did they test the pH of the soil and water?”
There were more papers flipping, likely someone presenting the results of those tests to him, “Yeah, the soil was a five-point two and the water was a seven-point eight,” he listed off for you.
While your knowledge of the pH of the soil in Iowa was limited, you did know that those levels were pretty on par for the northern Mississippi River. “O-kay,” you say, extending your vowels, “and they didn’t find anything else on the scene that points to corrosive materials. Hydrofluoric acid?” You posit, “No, you know what – maybe you should send me those files. My work email is encrypted, you can give it to Penelope.”
He speaks to someone else in the room with him and you resist the urge to ask him if he’s enjoying Iowa, “It’s sent,” he confirms with you.
Pulling up your email only takes a moment, and once you get over the initial shock of seeing a dead body on your computer screen, you lift your lab glasses to the top of your head in order to get a better look. “I mean,” you think for a moment, “those look like alkali burns to me. I’ve never seen them on bones before, but you should do a litmus test to check either way.”
“So, we rinse it with water?” He asks, seeking instruction from you in a way that makes you feel oddly powerful.
Your eyes widen, “No, no, no. If it’s a metal compound then it’ll be covered in a mineral oil, so rinsing it with water would actually make the burn worse.”
Pausing for a moment, you consider the possibility that Spencer didn’t have the luxury of time – he was trying to solve a murder, not do experiments in a lab.
“Alkali burns can be serious, it all depends on what caused them, and most are helped by rinsing with water. So, unless you have the time to test for metal compounds, I’d go ahead and rinse it. You might want to brush the damage to the bones with a dry brush first. If there’s lime on the bones it’ll foam, which not only will corrode the bones even further but it might release a toxic gas,” you have no idea how the corrosion would interact with bone marrow, but something tell you that you don’t want to know
“Wait a minute,” Derek interjects, being included in the conversation now that Spencer put the call on speaker, “I thought things like alkaline water were good for you.”
You scoff instinctively, “Oh, there’s no definitive evidence that shows alkaline water as having any real health benefits. Especially not the benefits that the internet says it has.” Straightening up in your stool, you continue, “In fact, there is evidence from the NIH that says drinking alkaline water could cause kidney damage. There’s a particular-“
“My bad,” he interjects, effectively stopping your rambling before it really took off, “I forgot whose girlfriend I was talking to.”
Groaning at your new vexation, you huff, “Oh, fuck off, Derek. Go kick down a door.”
Spencer quickly switches the phone back, “Thank you, angel.”
Squinting at the photos that were still on your laptop screen, a crude, disturbing thought came to mind, “You know, sparklers can cause alkali burns. It might be something to consider because of the diameter of the burns.”
Your boyfriend was silent on his end of the call for so long that you had to check and make sure the call hadn't dropped. “Did you say sparklers?”
“Yep,” you confirm, “like the ones you can get everywhere this time of year.”
He says something to Morgan, placing his hand over the receiver so you can’t hear, “There’s only one spot in this town, though. I’ve gotta go, see you soon.”
“Stay safe, please! I prefer your bones unburned,” you rattle off into the phone before it clicks, placing the phone back on the stand and deleting the crime scene photos from your inbox.
The front door to the apartment opens and shuts quietly, with Spencer under the assumption that you already went to bed, he was surprised to find you on the couch, nursing a cup of tea. “Hey, baby,” he chirps, unusually peppy for this time of night.
“Hey,” you say half-heartedly, threading your fingers through the handle of the mug.
Your somber tone gets Spencer’s attention, “What’s wrong?”
The slight panic in his voice causes your eyes to snap up to his, “Nothing,” you murmur. “It’s just… the woman who was in those pictures. There- the burns on her bones, they were signs of torture, weren’t they?”
You’d been thinking about the burns ever since Spencer showed them to you, “Yes,” he answers with a reciprocating softness, sitting down next to you on the couch. “The medical examiner concluded that she was burned antemortem.”
That woman had been burned alive by fireworks, sparklers had seared their way through skin and muscle until it finally met her bones. You blink a few tears from your eyes at the thought, “I like my lab, Spence.”
The confusion on his face was palpable, “I know you do.”
“I like my minimal human interaction and my chemicals, and I like knowing why certain things cause certain reactions. I like it when things make sense.” You take a deep, shaky breath, “Killing someone. Torturing someone with fireworks. That just doesn’t make sense to me.”
You had no interest in hearing the excuses that the killer had provided. You had no interest in hearing the psychological breakdown of that woman’s killer. Spencer knows that, “The photos got to you?”
Taking a sip from your mug, you nod solemnly, “I can’t stop thinking about the way it must have felt. Oh, the smell must have been horrible. That poor woman.” In theory, it was a ridiculous notion, killing someone with fireworks seemed neither probable nor possible. Yet here you are.
“But we got the person who killed her,” Spencer reassures you, resting his hand gently on your knee. “We couldn’t have done it without you,” he adds.
Your face warms at his compliment, “I wish I could have helped before she was killed.” You were grateful that Spencer hadn’t passed on any personal information about the woman, it was easier for you if you kept things in separate storage files in your mind.
Spencer hums, reaching out and sweeping a strand of hair behind your ear, “There’s always going to be another one. I’m sorry about the photos, I should’ve made sure Garcia only sent the necessary ones.”
Nodding absentmindedly, you look at him thoughtfully, “This will pass, but for tonight I just feel bad for the victim.”
“I can have Penelope share some of her favorite baby animal videos, if you’d like,” he offers softly, resting his head on your shoulder.
In return, you give him a small smile, “Well, I suppose it really can’t hurt.”

“Why do I have to walk backward?” You grumble while trying to balance the end of the plywood on your knee, pulling at your badge reel to unlock the lab door.
Spencer nods his head in the direction of the keypad, “That would be why.”
Rolling your eyes, you push the door handle down with your elbow before pushing the door open with your foot, shuffling your feet. “Honey, can you turn the lights on?”
Lifting herself up on her tiptoes, your daughter flips all of the switches on the panel, cringing at the bright fluorescent lights.
Together, you and Spencer hoist the science project onto one of the lab tables, careful not to knock anything over as the papier-mâché volcano rests in your professional lab.
You and Leah had stayed up until eleven last night finishing the last coat of paint, even entertaining a visit from her Aunt Penelope so that the finished project could have a fine dusting of glitter all over it. Your dining room was now permanently sparkly, but the look on your daughter’s face when she saw the finished project made the mess entirely worth it.
Spencer steps to grab your jugs of white vinegar from the car, propping the door open so he can bring the supplies for the baking soda volcano in.
Obviously, you weren’t going to use the full-size volcano now, but Leah had refused to travel without it and Spencer believes that saying no to her is an impossible task. “Mommy?” The little girl pipes up, playing with the stirring rod that you had just set in front of her.
“What’s up?” You ask, leaning your hip against the counter, gently reaching out and adjusting the bows adorning her pigtails that you’d put in her hair that morning.
She looks over at the wall, minding each of the posters that line your laboratory, “What is that?”
You follow her finger to see what she’s pointing at, smiling softly, “It’s the periodic table.”
Humming thoughtfully, Leah sets the stirring rod down and walks over to the poster, “It looks like the one at home.”
Nodding, you get a step stool out for her to stand on, “They’re the same poster, the one we have at home is just a lot smaller than the one I keep at work.” You explain to her, knowing she’s talking about the poster you keep in your home office. “Come on baby, let’s go get you a lab coat.”
Setting a hand on her shoulder, you guide her to the storeroom, “Woah,” she breathes. It’s not a positive reaction, her eyes flitter all around the room, a mess of lab coats and goggles.
“Okay,” you say, shoving your way through the space until you find your locker, pulling out your lab coat, as well as safety glasses for the whole family. Holding a coat up to her and having her pull it on, you put your own lab coat on before looking back to find your five-year-old drowning in polyester. Laughing slightly, you adjust the lapels of her jacket, “How does it feel?”
Leah looks down at herself, “Cool!” She exclaims beaming up at you and giving you two thumbs up. She skips out of the closet and heads back to her volcano, almost tripping over the extra fabric of the lab coat, but Spencer grabs her arm before her knees can hit the linoleum.
He smiles at her, “Are you okay?” Helping her adjust her coat, he kneels down to her.
“Daddy,” she cheers, completely ignoring his question for the sake of being five years old, “Look at my coat!”
Smoothing her hair back, Spencer’s eyes briefly meet yours before he looks back to Leah, “You look like mommy.”
In a fit of giggles, he scoops her up in his arms in an attempt to avoid a tripping hazard, but she just thinks it’s fun. He sets her down feet-first on the step stool you had gotten out for her.
“Here,” you say, handing him a lab coat for him to wear and setting the safety goggles you’d gathered on the countertop.
When your daughter came home in tears because she felt like she had been assigned the ‘most boringest’ project for the science fair, you and Spencer quickly decided that you’d try everything to make her baking soda volcano exciting. At the very least, you’d work together to make sure she has fun.
Leah puts her goggles on and looks up at you for her next instruction, watching you divide the baking soda and white vinegar into separate beakers, “So, what will happen when we add these two together?” Spencer quizzes, watching you make careful portions.
“It’s gonna fizz up!” She responds correctly, bouncing on her feet while you gently push the first two dishes in front of her.
You nod, “You can pour the white vinegar into the baking soda,” You nudge her gently, knowing that you measured just enough to reach the top of the beaker, but not enough to flow onto the counter.
She uses both hands to grip the beaker and pour the liquid out, and the immediate reaction surprises her so much that Spencer holds an arm out to keep her upright. He trains his eyes on her amazement as the foam dissipates and the water and sodium acetate are left in the glass. “Can I drink it?” She asks, frowning up at her dad.
“No,” you both answer immediately, a sort of parental reflex. If you don’t answer quickly enough, odds are she’d pick it up and try anyway.
Disappointed, her frown remains on her face while her eyes return to the countertop, timidly, she tugs on Spencer’s lab coat, prompting him to crouch down to her eye level, “What’s wrong, lovey?”
Her eyes nervously look around the lab, eyeing some of the cabinets before she takes a deep breath, “Can we make it pink?”
“The foam?” Spencer says curiously, eyes flickering up at you while you nod frantically, already thinking up options so that you could further individualize your daughter’s glitter volcano.
She rocks back and forth, “Can we?”
As soon as Spencer says yes, it’s like a hold on you has been released, unlocking some of the cabinets so you can grab more supplies from around the lab, you return to the station with an armful of things to try, and Spencer mutters something to Leah about you being a mad scientist, leading you to maturely stick your tongue out at him.
You set up four options, taking photos as you go so you can paste them onto her presentation board. The first one is just baking soda, but you added a touch of dish soap to the vinegar. The increase in bubbles seems to greatly please Leah, so you decide as a team that the final product should have dish soap in it.
The second one has manganese sulfate mixed into the baking soda, and if the pink salt altered the color of the foam at all, it doesn’t impress your perfectionist daughter.
The third one includes phenolphthalein, which you think has some real potential, based on the way Leah’s eyes widen at the sight of it combined with the vinegar. The liquid was almost a fuchsia color, and she gasps when she pours it in to find that the foam is white, “It’s gone?”
You nod, “The phenolphthalein when it’s in the vinegar is pink because it’s an acid, but as soon as you add the baking soda it becomes a basic solution, so…” Your voice trails off when Spencer starts shaking his head, and you look down to find that you have completely lost Leah’s attention. Instead of listening, she’s trying to pronounce phenolphthalein, tracing the letters on the black countertop.
“What do you have next?” Spencer asks, eyeing the tiny dropper bottle in front of you.
Picking it up, you drop some of it into the vinegar and hand it to Leah, “It’s food coloring.”
His eyebrows furrow, “Why do you have food coloring in the lab?”
You wrinkle your nose at him, the expression makes Leah giggle, “Mind your business.”
As a family, you watch the chemical reaction, the white of the foam mixing with the red food coloring to create the desired pink lava. “Oh,” your daughter says softly, “Thank you, mommy!”
Beaming down at her, you place your hands on your hips and sigh, “If you’d like, we can add glitter to the baking soda too.”
Wide eyes look up at you in amazement, brown eyes inherited from her father, “I love science,” she whispers.
Behind her back, you hold your hand out for Spencer, exchanging a silent fist bump—a quiet celebration between two scientists.

“Do you want to talk about it?” Spencer asked, watching as you braced yourself against the wall and kicked off your shoes, nudging them in the hallway until they were in place.
You hummed in response, “About what?” You inquired casually, proceeding to hand your coat on the rack and pull the sleeves of your sweater down. Avoiding his gaze, you bulldozed through to the kitchen, searching through the cabinets for an appropriate mug to make tea in.
He followed you to the kitchen, grabbing a mug and holding it out for you to take. You didn’t live here, but you knew your way around so well that someone might’ve gotten that idea. “Whatever it is that made you get so quiet tonight,” Spencer prodded, leaning over the kitchen counter and propping himself up.
Filtering through his tea collection, you faltered for a moment before continuing, picking a chamomile tea bag and flicking on the electric kettle. The two of you had just gotten back from dinner at Rossi’s, your second one since you and Spencer had started dating, where you watched Spencer spend hours doing magic tricks with Henry and Jack. You shook your head, watching the water in the kettle as it began to boil.
“Are you feeling alright?” Spencer asked, wondering if you had a physical ailment that was causing you to shut down. He had picked you up straight from work, maybe you were just exhausted.
This time you nodded, opening the wrapper for the tea bag and tossing the foil in the bin, “Yeah, long day,” you admitted, “Did you want tea?”
Spencer was quiet for a moment, watching as you instinctively grabbed another mug and prepared a cup of tea for him as well. It was starting to get chilly outside, so a warm tea was likely to have healing properties, “Have I done something?”
Now, you ignored his question, grabbing the mugs and bringing them over to the coffee table. You sat on the couch, nestling yourself into the corner and pulling a knit blanket over your lap. In your periphery, you watched him sit on the opposite side of the couch, and it was beyond your control when you finally spoke up, “Do you want kids?”
“I’ve never really given it much thought,” he responded, and you nearly flinched at his answer, convinced he was lying to save your feelings.
You shifted on the couch, staring down into the murkiness of your tea, “What does that mean?”
He pressed his lips in a thin white line for a moment as if he were considering his options, “I’ve never really been in a relationship where that was a discussion to have, so I’ve never done an in-depth evaluation of whether or not I want kids of my own.” He set his mug down on the coffee table and turned to you, “But I take it you have.”
Slowly, you nodded, skimming the handle of your mug with the pad of your thumb, “I don’t want kids,” you whispered, closing your eyes as soon as the words were out there.
Spencer was quiet, and you were afraid that the finality in your voice would be the reason you lost him forever. No more BAU family dinners at Rossi’s. No more phone calls seeking help on a case. No more whispering nonsensical science puns to each other in the middle of the night when you should be asleep. You were surprised when he answered, “That’s okay with me.”
You lifted your head, craning your neck to the side so you could determine whether or not he was messing with you. Instead, earnest brown eyes stared back at you, “It is?”
He shrugged lightly, “Admittedly, I’m not too fond of the idea of choosing between a family and the BAU. I’ve seen enough wedges driven and bridges burned to know that that’s not something I want to experience first-hand.”
“It’s just never felt like the right thing for me,” you elaborated on your own feelings, still not convinced of his. “Sometimes I… I think I’m too selfish to be a mother,” you confessed, setting your mug down and pulling your knees to your chest. “I see people around me and the things they sacrifice for their children, and I don’t think that could ever be something I do, Spence. It’s not in the cards for me.”
Cocking his head at you, Spencer studied you for a moment, “If you don’t want to be a mother, then you don’t have to.”
Your eyes burned fiercely at his words, so shocked by his response to what had sent previous boyfriends running for the hills. “I think maybe you should take some time to think about this because you said you never have before,” you advised him cautiously, setting your chin on your knee.
He shook his head dismissively, “I don’t need to think about it. If it’s a choice between you and some hypothetical children, then it’s really no choice at all.”
Closing your eyes, you let tears fall freely down your cheeks, “I just don’t want you to wake up someday and resent me for not giving you children. I don’t want you to roll over in bed and think about how I’ve somehow failed you.”
It was that statement that prompted Spencer to reach out to you, he tenderly looped an arm around your shoulders and pressed a kiss to your temple. “I could never resent you for making a decision about yourself like that, do you understand?”
“You’re just so good with them,” you bemoaned, recalling the flashing images of Spencer doing card tricks for the kids and refusing to reveal his secrets to them.
Spencer smiled softly at you, “It’s easy when you don’t actually have to do the raising of the children. I’m more than comfortable with my title of godfather and uncle.”
“But what if you need more?” You asked desperately, still horrified by your hypothetical day where Spencer wakes up with hate in his heart.
His other arm looped around you, pulling you closer to him, “Trust me when I say this: you are more than enough for me.” He squeezed you gently, “I can be good with kids and be perfectly content with never having any of my own. Those two things can coexist.”
Nodding absentmindedly, you leaned your head onto his shoulder, “Thank you,” you breathed, silent tears still streaming down your cheeks only to be swept away by your boyfriend’s deft fingers.
