Spencer’s alarm goes off at 6:15, but you’re pretty sure he’s been awake for ten minutes already and just pretending not to be so he can keep his arm around you.
“Turn it off,” you mumble into his chest.
“I got it,” he says as he reaches for the clock.
You crack an eye open. “Too early.”
He ignores your complaint in favor of dipping his head to kiss your forehead, then your temple, then the corner of your mouth. You kiss him back, slow and lazy, one hand curling in the soft cotton of his t-shirt.
“If we don’t get up now, we’ll be late,” he says, very much not moving to get up.
“You say that like you didn’t design your alarm timing around a twenty-minute buffer,” you reply, sliding your leg over his.
“Sixteen-minute buffer, actually,” he corrects. “We typically spend an average of seven minutes kissing before I spend the other nine between your—”
“Spencer!” you shriek, cutting him off before he can finish a statement like that at six in the morning.
He smirks. “I was just providing data.”
You pinch his side. “Provide less.”
He laughs again, sleepy and warm, and grins like he’s proud of getting you flustered.
You kiss him again. It’s easier now that the part where you pretend not to want to stay has worn off. You just want to stay, and you let yourself.
When you finally peel out of bed, it’s with mutual groaning and the kind of reluctant separation that would be disgusting if it were anyone else. He presses a quick kiss between your shoulder blades as you swing your legs over the side of the mattress; you pretend it doesn’t make your chest do something stupid.
By the time you’re dressed and make your way out of the bedroom, Spencer’s apartment smells like coffee and toast. He’s in the kitchen in a button down and slacks, tie draped around his neck, reading something in the newspaper with a little furrow between his brows. There’s a mug waiting for you — your mug, chipped on one side, living here now without discussion.
You snag a piece of toast off his plate, bite into it, and lean your hip against the counter while he wrestles with his tie. It’s a new one — navy with small, neat polka dots.
“Come here,” you say, setting your mug down.
He steps closer automatically when you hook two fingers in his belt and tug him in. You untie the knot and redo it, straightening it with careful precision. He watches your face like you’re doing something much more interesting than fixing his tie.
“What?” you ask.
“Nothing,” he says. “I just… like you here.”
You roll your eyes because the alternative is something mushy, but then you lean in anyway and let your lips find his.
The kiss is soft and familiar and still somehow manages to make your knees a little shaky. He tastes like coffee and toothpaste and home, which is a terrifying thought you refuse to examine this early in the day.
He breaks away first, forehead resting against yours. “We should go.”
“Yeah,” you say, not moving.
A beat passes, then another long kiss. Eventually you both laugh, step back at the same time, and pretend you’re ready for reality to hit.
You grab your jacket and badge off the hook, he grabs his satchel and keys, and you walk out the door together.
—
By the time you pull into the Quantico lot, the radio is off and his hand is resting, casual and warm, on your thigh. You let it stay there until you’re close enough to see the building, then you nudge it away and give him a look that says later.
He gives you one back that says I know.
The practiced routine kicks in — you get out and head inside first, he waits three-and-a-half minutes before doing the same.
Spencer barely makes it to his desk before Rossi appears beside him like a well-dressed shadow.
“Ready to go?” Rossi asks, coffee in hand, already halfway turned toward the bullpen doors.
They’re headed to the academy building across campus, today’s guest lecturers for a criminology training. Spencer always pretends he’s indifferent to that sort of thing, but the second he’s in front of a whiteboard, he lights up.
Spencer blinks, then nods. “Yes. I just need—”
“Your notes are in your bag,” Rossi says. “You sent me five drafts already. Come on, kid, the cadets await.”
Spencer glances in your direction automatically. You lift your eyes just long enough to catch his and tip your chin, a small, private acknowledgment no one else would notice.
He smiles — barely there, but there — and then heads out with Rossi. You watch them go, then drag your focus back to the report in front of you.
You get maybe three minutes of peace.
“Greenawaaay,” Garcia sings, appearing at the edge of your peripheral vision like a colorful mirage.
You don’t look up yet. “If this is about your whipped cream experimentation with Kevin, I already told you I’m not certified in exorcisms.”
“It’s not about the whipped cream,” she says. “It’s much more important than the whipped cream. Which should tell you the stakes here are astronomical.”
You sigh, close the file, and finally turn. JJ and Prentiss are hovering behind her with matching she-already-recruited-us-but-we-don’t-know-what-for expressions. Morgan leans against the nearest desk, arms folded, clearly already in on whatever this is.
“What did you do?” you ask.
“Me?” Garcia bats her lashes. “Nothing. But we’re about to make history. Come on.” She jerks her head toward the hallway. “Top secret meeting in my office.”
You narrow your eyes. “I’m on the clock, Garcia. I have work to do.”
“As do I,” she says. “This is… related to work. Trust me.”
You should say no. You should go back to your paperwork. Instead, curiosity wins and you slide out of your chair.
Garcia herds the four of you down to her lair like a cheerful, bedazzled sheepdog. The door closes behind you with a heavy thud, the lights of her monitors bathing the room in neon. On the far wall, there’s a corkboard you don’t remember seeing before.
At the top, in big, bold letters outlined with glittery tape, it says:
OPERATION MYSTERY GIRL - O.M.G.
Garcia plants herself in front of the board, hands on hips. “Welcome, my beloved profilers and communications liaison, to the inaugural briefing of O.M.G.!”
JJ presses her lips together, clearly trying not to laugh. Morgan isn’t even pretending to not be thrilled. Prentiss looks like she’s just been handed front-row tickets to a train wreck.
“Please tell me this isn’t what I think it is,” you say.
“This,” Garcia announces, pointing dramatically at the corkboard, “is a fully serious, very important investigation into the case of Dr. Spencer Reid’s mysterious secret girlfriend.”
You blink. “You’re kidding.”
“Do I look like I’m kidding?” She gestures dramatically to the board again. It’s already populated with printed photos, sticky notes, and colored yarn connecting pins like you’re standing in front of a conspiracy theorist’s wet dream.
At the bottom is a sheet of paper featuring a stick figure of a woman with a giant question mark over her face. Around it: headings that read EVIDENCE SO FAR, POTENTIAL OCCUPATIONS, and VIBES in Garcia’s handwriting.
You step closer despite yourself.
Under EVIDENCE:
Suspiciously happy like all the time
Volunteering for less overtime than usual
New clothes??!!
His aura just screams I’M IN LURVVV
“Some of this is actually pretty accurate,” Prentiss says, leaning in.
“I’ve been monitoring his behavior for weeks,” Garcia says proudly. “The data doesn’t lie. Our boy genius is smitten, and he is hiding her from us.”
Morgan shakes his head. “He’s definitely hiding something. We’ve been saying that for a while. And at O’Keefe’s the other week, he didn’t exactly deny it. He just said ‘no comment,’ which means there’s definitely a girl.”
“He has a right to privacy,” you point out, mostly because you’re trying not to gnaw through your own tongue.
“Absolutely,” Garcia says. “He has the right to privacy, and I have the right to gossip with my friends about our other friend. Both things can be true.”
Prentiss snorts.
Garcia taps the POTENTIAL OCCUPATIONS column, where there are several options listed already:
Kindergarten teacher
Librarian
Baker
Social worker
“Seriously? You think he’s dating a kindergarten teacher? A librarian?” you ask.
JJ lifts a shoulder. “He does like to read.”
“And he’s good with kids,” Morgan adds. “Makes sense he’d go for someone sweet and gentle like that."
“It’s probably someone outside the FBI,” Prentiss proposes. “Normal job. Normal hours. No guns.”
“She definitely wears super cute colorful cardigans,” Garcia adds, already scribbling it down under VIBES. “And I’d venture to guess that she bakes cupcakes when she’s stressed. Smells like vanilla!”
“Vanilla,” you echo, deadpan.
JJ tilts her head. “You don’t think he’d be into someone like that?”
You shrug like it’s theoretical, like your heart isn’t doing something unpleasant in your chest. “He might be, I don’t know. But I think he needs someone who can actually handle the job. The hours. The… everything. This kind of life isn’t exactly gentle.”
“Exactly,” Garcia says. “Which is why she’s gotta be gentle. She provides a counterbalance. Yin and yang, crime and cupcakes. It’s poetic.”
She writes CUPCAKES under VIBES.
Morgan points his pen at the pinned drawing of the stick figure woman. “Come on, Greenaway. You spend a lot of time with him. Help us out.”
“I do not spend a lot of time with him,” you deny automatically.
Four pairs of eyes look at you.
You lift your hands. “Fine. I spend an appropriate amount of professional time with him. Not my fault Hotch pairs us together a lot.”
“Point is, you know him. So, from a purely hypothetical standpoint,” JJ says, “what kind of person do you think he’d be happy with?”
You stare at the board for a moment, at the fake girl they’ve built out of cardigans and vanilla extract. Then you pick up a pen.
“Someone smart,” you say. “He’d need that. Someone who doesn’t treat him like a walking encyclopedia but also doesn’t get lost or zone out when he goes off on a tangent. Someone who doesn’t flinch when things get ugly,” you continue. “You all know what this job does. You don’t get to just… opt out of the darkness. If you’re with him, you’re in all of it.”
You tap the pen against the board, then force your tone lighter. “And yeah, okay, probably someone nice.”
Garcia grins, scribbling down NICE under VIBES and functionally ignoring the rest of what you said. “See? This is why I invited you. You have insight!”
Morgan grins. “So we’re in agreement. She’s smart, sweet, likes kids, bakes.”
“And probably has no idea how lucky she is,” JJ adds.
You swallow back the instinctive no, she definitely knows she’s lucky and say instead, “Can I go back to work now, or are we building a composite sketch?”
Garcia swats the air. “This is just Phase One, my fine furry friend. We will reconvene later. In the meantime, I expect you all to investigate.”
You roll your eyes, but there’s no real bite in it. “Great. Can’t wait to see what Phase Two has in store.”
As you step back, your gaze catches on the stick figure again. On the glitter, the stickers, the ridiculous heading — O.M.G.
According to the board, Reid’s mystery girl should be someone who wears cardigans. Smells like sugar. Teaches kindergarten.
Definitely not someone like you.
You shove that thought down where it belongs, under seven layers of scar tissue and denial, and head back to the bullpen like nothing in here touched you at all.
—
The rest of the morning unfolds like any other day at the BAU, if you ignore the fact that one of your coworkers has unknowingly built a conspiracy wall about you.
You try to ignore it.
You work a consult. You write up a report on last week’s case. You argue with a detective over the phone until he backs down, and when you hang up, Morgan’s watching you like: damn, remind me to never piss you off.
“You good?” he asks.
“Peachy,” you say, tossing the file onto your desk. “Please tell me Garcia found a new hobby in the last hour.”
He grins. “Not a chance. She’s real committed to this one.”
You roll your eyes and open your email.
There’s a subject line from Garcia that reads: “O.M.G. – Phase Two Meeting Tomorrow - Agenda Enclosed!” with three heart emojis.
You don’t open it. You’re not that masochistic.
Around noon, your phone buzzes against your desk. You assume it’s another follow-up from Garcia and flip it over, already cringing. Instead, it’s Spencer.
Spencer: Cadets have already asked 3 questions that make me concerned for the future of law enforcement.
You huff out a quiet laugh before you can stop it, shoulders loosening.
You type back under the desk.
You: important news from the home front: i am currently the unsub in an unsanctioned profiling experiment being conducted out of garcia’s lair
There’s a long enough pause that you can imagine him reading it twice, brow furrowed.
Spencer: …What?
You: penelope has formed a task force
You: codename: operation mystery girl
You: acronym: O.M.G.
You: there’s glitter. so much glitter
You: and specific instructions not to tell you about it. oops
This time, his reply is almost immediate.
Spencer: Why can’t I know?
You: because you’ve been “suspiciously happy” so they’ve decided that gives them grounds to reverse-engineer your love life
You: they’re profiling your “type.” your mystery girl.
Another beat. You can practically feel him flushing through the screen.
Spencer: What have they concluded so far?
You: that you’re dating a bubbly, perfect kindergarten teacher who smells like vanilla
There’s a full minute of silence this time. You picture him in some Academy auditorium, phone in his hand under the desk while Rossi lectures about offender typologies.
Finally:
Spencer: I don’t even like vanilla that much.
You laugh under your breath and stare at that for a second, heat curling low in your stomach for absolutely no good reason as his second text comes through.
Spencer: I prefer more complex flavors.
You roll your eyes at your phone, because of course he somehow made that sound unintentionally sweet and slightly filthy without even trying.
You: stop flirting with me during class
You: you’re supposed to be educating the next generation of the fbi
As if on cue, Hotch’s door opens and he steps out into the bullpen, scanning the room. You turn your phone face-down on your desk.
By late afternoon, O.M.G. has evolved. Every so often you catch someone making a note — Garcia walking by while scribbling on a sticky, JJ whispering something in her ear, Prentiss and Morgan analyzing Spencer’s desk from a distance.
It’s fine. It’s all stupid and harmless and fine.
Your phone buzzes again around four while you’re in the hall heading back from the bathroom.
Spencer: Wrapping up here, should be back soon. Any further developments on the O.M.G. front?
You glance down the hall towards Garcia’s office. The door is closed, a faint glow spilling out from beneath it like a witch’s cave.
You: more of the same
You: i’ll fill you in tonight
You hesitate, then tack on one more message before you can talk yourself out of it:
You: miss you
It’s reckless and feels entirely too honest, but your thumb hits send anyway.
The reply comes before you’ve even locked your phone.
Spencer: I miss you too. See you soon.
You swallow, looking around like the words might be visible in the air, but no one’s looking at you. No one has a clue.
Yet.
—
By the time you make it to Spencer’s apartment after work, your brain feels like it’s humming inside your skull.
You kick the door shut with your heel, toe your shoes off in the entryway, shrug out of your jacket and scarf and hang them on the hook you’ve claimed as your own. Spencer drops his satchel by the couch and heads for the kitchen.
“Dinner,” he calls, opening the fridge. “Option A: leftover lo mein. Option B: grilled cheese. Option C: both.”
“C,” you pick.
He smiles faintly and pulls out the takeout container. It’s all so normal — him moving around the kitchen, sleeves rolled up, you leaning your hip against the cabinets as you watch him. This is your life now: FBI agent by day, domestic lovergirl by night.
You watch him butter bread and portion out noodles like he’s solving a complex equation. He glances up.
“You said you’d fill me in,” he reminds you. “On O.M.G.”
You snort. “Right. Your fan club.”
He raises his eyebrows. You sigh and attempt to pick the least sharp version of the recap you’ve been brewing in your head all day.
“Garcia built a case board,” you say. “There are doodles and glitter tape and stickers. She has lists pinned to it for ‘Evidence So Far,’ ‘Potential Occupations,’ and ‘Vibes.’”
He blinks once. “…Vibes.”
“Vibes,” you confirm. “And according to our coworkers, apparently the ‘vibe’ is that you’re secretly dating a kindergarten teacher slash librarian slash cupcake baker who smells like vanilla and wears colorful cardigans and definitely doesn’t carry a gun or have years of trauma to work through in therapy.”
He pauses in the act of flipping a sandwich. “Oh.”
“Yeah. Oh.” You pick at a chip in the countertop.
“And what did you contribute to the investigation?” he asks.
You shrug like it doesn’t matter. “That whoever you’re with would have to be smart. And able to handle the job. And not treat you like you’re made of glass. Clearly, my influence was minimal.”
The grilled cheese sizzles. The lo mein goes in the microwave. Silence fills in around it, heavy and familiar.
You eat on the couch, plate balanced on your knees, a National Geographic documentary playing low on the TV.
You make jokes at first. You tell him about Prentiss and Morgan’s intense study of his desk for “data collection” and Garcia’s email subject lines. Spencer laughs in all the right places. He looks at you more than he looks at the screen.
But by the time the plates are empty, the jokes have dried up.
You stack the dishes and take them to the sink, rinsing them off like the hot water might scald the thoughts out of your head. When you look up, he’s still on the couch, watching you with that careful focus of his.
“What?” you ask.
“You’re doing that thing,” he says.
“Please specify which thing,” you say. “I have a lot of things.”
“The thing where you brush something hurtful off like it’s funny but then go really quiet and your shoulders get all tense.” He pats the cushion next to him. “Come here.”
“I’m fine,” you say automatically.
“I never said you weren’t.” His voice stays soft, but there’s a thread of seriousness underneath it. “I said to come here.”
You sigh and drop onto the couch beside him with more force than necessary. He shifts closer, thigh warm against yours. His hand finds the back of the couch behind your shoulders, not quite touching you yet.
“So,” he says. “What’s bothering you? And don’t say ‘nothing,’ because we both know that’s not true.”
“It’s stupid,” you grumble, staring at the coffee table.
He gently lifts your chin with his finger. “Okay. Tell me anyway.”
You chew the inside of your cheek, throat tight. You’ve been replaying it all day — the board, the stick figure, the list of traits that are a complete juxtaposition to your entire personality.
“I…” You trail off and try another angle. “The team loves you. They just want you to be happy. It’s sweet, honestly. A massive overstep and an insane invasion of privacy, but still sweet. I understand their curiosity.”
“But,” he prompts gently.
You exhale, sharp. “But… they built you a perfect imaginary ideal girlfriend, and she’s nothing like me.”
He’s quiet. You push on before you can lose your nerve.
“Like, not even a little bit,” you say. “She’s soft and gentle and bakes when she’s stressed and doesn’t know what a glock looks like. She smells like vanilla.” The word tastes bitter on your tongue. “And the thing is, Morgan and Garcia and JJ and Prentiss know you. Like, really well. They’re your best friends. So if that’s the woman who pops into their heads when they think about who’d be good for you—” You break off.
When you look up, his eyes are still on you, open and steady.
“When they eventually find out it’s me,” you go on, forcing the words out, “they’re going to look at you like you’ve lost your mind. Like you traded in a cupcake for… I don’t know. A Molotov cocktail or something.”
“You don’t honestly think,” he says, “that they sat there and consciously decided, ‘Reid should be with someone who is the total opposite of Greenaway.’”
“No,” you say. “I think they didn’t think of me at all.”
The words hang there, more naked than you meant them to be.
He goes very still.
“Not that I wanted them to think of me and figure it out, but still.” You stare resolutely at the coffee table. “And, like, I get it. I’ve spent a long time cultivating a vibe that says ‘do not perceive me unless you want to get bit.’ I don’t exactly radiate ‘nurturing life partner’ energy. It would almost be funny if it didn’t feel like—” You motion helplessly at some vague point in front of you. “Like confirmation,” you say. “That I’m wrong for you. That when they do eventually find out, they’re going to wonder how badly you hit your head.”
There’s a prickling behind your eyes. You blink hard, once, twice. It doesn’t help much.
“And I hate that it’s getting to me,” you say. “I don’t care what people think. That’s, like, my whole thing. I have built an entire personality around not giving a shit. But I…” You flex your hands, fingers curling against your knees. “I care what they think of you. And of you with me. And apparently that’s enough to scramble my brain, because now I’m sitting here wishing I could be some fucking vanilla-cupcake-librarian for you because you deserve someone that sweet and soft and kind, but that’s— that’s not who I am. I don’t know how to be that girl. And I am so fucking tired of being the wrong kind of girl in every room.”
There’s a long moment where the only sound is the TV and your own breathing, too loud in your ears.
Then Spencer moves.
He reaches over, gently pries your hand away from your knee, and laces his fingers through yours. His palm is warm. His grip is firm without being possessive.
“Look at me,” he says.
You do. It feels like standing on the edge of a roof and choosing, deliberately, not to step back.
“You’re right, they do know me,” he says. “But they don’t know what it feels like to be in my apartment at three in the morning when my brain won’t shut off and you stay up with me just so I’m not alone. They don’t know what it’s like to sit in a car with you at a crime scene and have you make the darkest possible joke at exactly the right moment. They don’t know how it feels when I start spiraling and you say, very firmly, ‘Reid, eat something,’ and shove a granola bar into my hand.”
You start to object. “That happened, like, one time.”
“It was three times,” he says. His thumb strokes along the side of your hand absentmindedly.
“They’re still a bit stuck on the version of me that existed before… a lot of things. Before Tobias Hankel. Before Gideon left. Before losing people changed the way I look at everything. They still see the kid who needed to be protected from himself.”
“Sometimes you still are that kid,” you say softly.
“Sometimes,” he agrees. “But I’m also a man who knows what he wants. Who he wants.” His eyes are steady on yours. “And it’s you. It’s been you for a long time.”
Your throat tightens.
“They want me to have someone gentle,” he says. “And I get why. But gentle doesn’t necessarily have to mean cupcakes and vanilla and kindergarten.” He tucks a strand of hair behind your ear. “You’re gentle with me in all the ways that matter. You know when to challenge me and when to just… be here.”
“So you’re saying you don’t want a cupcake,” you say slowly.
“I’m saying I don’t want to be handled,” he corrects. “I don’t want to be someone’s fragile project. I don’t need to be saved from my own life by a nice woman in a cardigan.”
He leans in a little, eyes not leaving yours.
“I chose you,” he says. “Not because I’m convinced you’re secretly soft underneath it all and one day you’ll transform into their idea of what my life should look like. I chose you, completely as you are. Sharp and stubborn and infuriating and the only person who’s ever told me to shut up not because you didn’t care what I had to say, but because you wanted to kiss me so badly you couldn’t wait."
Heat flickers under your skin at that memory. Your eyes sting again. You blink hard.
“They love me,” he says with a nod. “You’re right. But they also love you. They trust you with their lives. They’ve seen you bleed for this team. Do you really think that when they find out I’m with someone who understands all of that, who gets it down to the bone, they’re going to… what? Stage an intervention? Tell me I should hold out for someone better?”
You look away, jaw tight.
“If I didn’t want you,” he says, voice even, “I wouldn’t be with you. If I thought you were wrong for me, I wouldn’t let you into this part of my life.” He squeezes your hand. It’s grounding, the pressure. “I’m not going to look at Garcia’s corkboard and suddenly decide I made a mistake. I’m in this because I want to be.”
You swallow, hard. A traitorous tear finally escapes despite your best efforts; you swipe it away with the heel of your hand before it can go rogue.
“This is so embarrassing,” you mutter. “I’m mad at a fucking bulletin board.”
He smiles, small and fond. “You’re not mad at the board.”
He shifts closer, finally letting his arm drop around your shoulders, pulling you in until you’re halfway in his lap.
“I just don’t want to be the wrong choice,” you whisper.
“You’re not,” he says. No hesitation. “You’re the right one. And if that conflicts with our friends’ wild imaginations, then that’s their problem to solve. Not ours.”
You swallow, breathing uneven. He’s so close you can count his eyelashes. You let your head tip against his shoulder as his thumb draws idle circles on the back of your hand.
“Okay,” you say eventually, almost too quiet to hear. “But if they look at me like I’m a bad idea when they eventually find out, you’re in charge of reminding them I’m not.”
“I can do that,” he promises.
You stay like that for a while — documentary murmuring in the background, the universe shrunk down to the circumference of his arm around you and the steady rise and fall of his chest. At some point, he turns his head and presses a kiss into your hair.
“You know Garcia’s going to put glittery heart stickers around my face if she ever adds me to that board,” you mumble against him.
“I know,” he says. “And I’m so keeping it if she does.”
You pinch his side. He yelps, then laughs, then presses another kiss into your hair.
Let them have their glitter for now, you think to yourself. Let them build their wrong profile. It doesn’t change the fact that you’re here, and he’s here, and you’re choosing each other.
—
Rossi’s email hits your inbox on Thursday morning, wedged between a case update and a training memo.
BAU Pasta Night at Villa Rossi: Saturday. 6pm. Mandatory attendance.
You read it twice. There’s something about dinner at Rossi’s that feels less like an invitation and more like a command.
Your phone buzzes with a text five minutes later.
Spencer: Did you see Rossi’s email?
You stare at the screen longer than you need to, then type back:
You: yep
You: guess we’re having pasta this weekend
Once Saturday night hits, Garcia is on Spencer before he can even take his coat off in Rossi’s foyer.
“REID,” she announces, planting herself in front of him with the kind of intensity she usually reserves for hacking and cross-referencing. “You came alone.”
Spencer’s mouth opens. Closes. “Hi, Garcia.”
Morgan appears behind her with a glass of wine, already grinning. “No plus-one, man? C’mon.”
Emily lifts her eyebrows in amusement. JJ’s smile is softer, more sympathetic than nosy.
You keep your face blank and slip past them toward the kitchen, waving awkwardly to Hotch as you pass by the living room, because if you have to stand there and listen to this, you will commit a felony.
Rossi intercepts you with a dish towel over his shoulder and a look that says I got you, kid.
“If you’re looking for a way to escape Penelope’s witch hunt, go ahead into the cellar downstairs and pick out another bottle of red,” he says mercifully. “Barolo or Chianti preferably, but it’s your choice."
“Yes, sir,” you say sarcastically, and take the out.
The basement is cooler, quieter. You let yourself breathe for a minute, fingers trailing over labels, pretending you’re here for the tannins.
Meanwhile, upstairs, Spencer is doing his best impression of a man who is not currently being cornered by three BAU agents and one extremely glitter-motivated tech analyst.
Garcia doesn’t even bother easing in.
“Okay,” she says, clasping her hands. “We have respected your privacy for—”
Morgan coughs. “We have attempted to respect your privacy.”
Garcia glares at him, then refocuses on Spencer. “—for a completely appropriate amount of time. But I simply cannot wait any longer. In my heart of hearts I know you’re seeing someone, and I’m DYING to know who she is.”
Spencer rubs the back of his neck. “This is, uh… really none of your business.”
Emily leans against the counter, entertained. “You’re surrounded by profilers, Reid. Being in other people’s business is kind of what we do best.”
JJ steps in a little. “Look, Spence, you don’t have to tell us anything you don’t want to,” she says, and she means it even though Garcia’s threatening her with dagger eyes. “But we’re your friends. We notice when something changes, and we just want the chance to be happy for you.”
Spencer’s ears go pink. “I—I know. It’s just— It’s private.”
Garcia’s eyes widen theatrically. “So she IS real! Private means real!”
Morgan tilts his head. “C’mon, fess up. You seeing someone, pretty boy?”
Spencer hesitates for an awkward beat, running through the options in his head. He supposes that confirming the existence of a significant other isn’t the worst idea in the world, considering they’ve already pretty much figured it out, and it’s not like he has to tell them who the “mystery girl” is. That’s a boundary line he can draw and stick to. Plus, maybe they’ll chill out on O.M.G. and leave you some room to breathe if they at least have a few nuggets of information to hold them over for a bit.
“Yes,” he admits finally. “I’m…seeing someone.”
Garcia makes a sound like she’s about to ascend. “OHHH MY GOD. I KNEW IT.”
“So,” Emily says. “How long has it been?”
Spencer exhales. “A… while. Things started slow, so it’s somewhat hard to quantify.”
As if he doesn’t know the exact amount of time down to the minute that’s passed since you first kissed him in Ohio.
Morgan’s cheeky grin softens as he claps Spencer’s shoulder. “I’m happy for you, man,” he says.
Spencer nods and looks down, like he doesn’t know what to do with that. JJ’s expression brightens in a way that’s genuinely excited for him.
“Well,” Garcia says, leaning in like she’s about to jump into full-on detective mode. “Tell us about her! I want to know everything.”
Spencer’s eyes flick up. “I—”
“Not actually everything. We’re not asking for her social security number,” JJ clarifies. “Not even her name. Just…are you happy? Is it going well?”
Spencer nods, the corner of his mouth tipping up despite himself. “Yeah,” he says quietly. “It’s…good. Really, really good.”
Garcia’s voice turns unexpectedly soft. “Is she good to you?”
Spencer doesn’t hesitate. “Yes.”
Emily taps her fingernail against the counter. “What sorts of things do you two do? Do you go out? Stay in?”
“Both,” Spencer says. “We do, uh, normal things.”
Garcia squints. “Define ‘normal,’ because your normal includes reading hundred-year-old Russian novels for fun.”
He gives a small, helpless shrug. “We… we go on walks. Run errands. Go out to eat. There’s this little Italian restaurant in Georgetown she really likes. But… we also stay in a lot. We cook together sometimes. Talk. Read. Watch movies.”
“What kind of movies?” JJ probes.
Spencer thinks of you engrossed by a classic horror film or picking apart some terrible romcom with surgical cruelty, pointing out every dumb decision while somehow still being fully invested. He does not say that out loud.
“Uh, anything, really,” he says instead. “She made me watch Pulp Fiction recently, and I showed her a documentary about black holes last weekend. She… likes indulging my interests.”
Emily’s eyes flicker with satisfaction at that. JJ files it away. Garcia is practically vibrating.
Morgan jumps in next. “So, you planning on bringing her to one of these things eventually?”
Spencer’s throat bobs. “…Eventually.”
“In the meantime, I need more. What does she like?” Garcia presses. “What’s her favorite—food, music, whatever. Give us something, Reid! One harmless little detail.”
Spencer’s brain scrambles for something that feels safe. Something that won’t point to you. Something small.
“She… she has a bit of a sweet tooth,” he admits. “Brownies, cake, cookies… you know. But she hates warm fruit. Something to do with the texture. We went to a diner once where the waitress gave us free slices of pie, and she picked out all the fruit and just ate the crust and ice cream.”
Emily laughs. “That’s unhinged.”
Garcia clutches her heart. “Oh, a woman with a quirk! I just know I'm going to adore her already.”
Spencer’s eyes flick toward the cellar door for the briefest of seconds — instinctively, as if his gaze is trained on you like a magnet — before looking back at his nosy friends with his signature awkward, tight-lipped smile.
“Yeah,” he says. “I have a feeling you will.”
—
When you come back upstairs with a bottle of Barolo, the evening has already moved into that easy, warm groove: plates clinking, voices overlapping, Rossi refilling wine glasses.
You laugh at something JJ says. You argue with Emily about her taste in horror movies. Spencer watches you like he’s trying to memorize your face. As if he hasn’t already committed every inch of it to memory.
By the time the pasta plates are cleared and Rossi heads into the kitchen to grab dessert, you’ve almost forgotten about O.M.G. entirely. The team has, mercifully, taken it easier on Spencer after the conversation you missed while seeking refuge in the wine cellar.
Whatever he said to shut them up, it must’ve worked, you think to yourself.
Rossi returns to the dining room and sets a slice of apple pie in front of you. “Made from scratch,” he boasts.
You eye it. The apples are glossy and soft. Wrong texture. Wrong temperature. But the crust looks deliciously sugary and flaky and you’re not about to insult Rossi in his own home mansion, so you manage a polite “Thank you” and pick up your fork.
Across the table, Spencer freezes.
Not a subtle freeze — no. It’s a full, wide-eyed, deer-in-headlights freeze.
He clears his throat too loud. Knocks his fork against his plate. His foot finds your ankle under the table with a series of frantic little nudges.
You glance up, confused, eyes clearly asking what the heck is your problem.
He’s staring at your plate like it’s an unpinned grenade.
His mouth opens. Closes. He tries again, smaller, more desperate: “Uh—”
What? you mouth, eyebrows raised.
His eyes flick back and forth — pie, you, pie, you — like he’s trying to telepathically beam a message directly into your skull. But there is, unfortunately, no universal signal for if you eat your pie like a feral raccoon our coworkers are 100% going to figure out our secret so please just be normal this one time, so you just stare at him blankly.
Weirdo.
You gently kick his foot away — more confused than annoyed — and turn back to your plate.
And then you do what you always do.
You begin to push the warm apples to one side of the dish with the edge of your fork, methodically separating fruit from crust like you’re field-stripping a firearm.
Spencer’s face goes beet red in anxious anticipation, but the room doesn’t go silent all at once.
It’s staggered. Like a line of well-spaced dominos, toppling one after another in perfect succession.
Garcia notices first. Her whole face lights up, brows practically shooting up to her hairline. A strangled noise catches in her throat, and her hand clamps over her mouth like she’s trying to keep herself from screaming.
JJ freezes mid-bite, fork suspended, eyes wide and snapping to Spencer.
Morgan’s grin falters into disbelief. “No way,” he says, like he’s arguing with reality.
Emily’s jaw goes slack. “Oh,” she breathes. Then her eyes sharpen, bright with dawning glee. “Ohhh.”
You look up at the sudden weirdness and find four faces locked on your plate like you’ve just confessed to arson.
“What,” you ask carefully, “is happening. Why are you all staring at my pie.”
Morgan points his fork at your dish and turns to Spencer. “Reid,” he says, voice pitched with amusement, “didn’t you literally just tell us your girl does that? That she won’t eat warm fruit?”
Spencer shuts his eyes for a second — brief, pained — like he’s watching himself die in third person. When he opens them, he looks straight at you.
Pure apology. Pure guilt.
He winces. “I… I didn’t know there was going to be pie.”
Something in you goes cold and then hot at the exact same moment you catch up to what’s going on.
For half a second, your brain offers you the classic Greenaway solution: vanish. Run and never look back. You can practically feel the panic trying to crawl up your throat, because this is what you were dreading — the second everyone knows, they get to have opinions. They get to look at you and Spencer like a math problem and decide you don’t add up.
Except… they’re not at all looking at you like you’re wrong for him.
You scan the room. Garcia’s smiling so big it looks painful. JJ’s gaze is warm, not sharp. Emily looks like she just won a bet she never told anyone she made. And Morgan is staring like he can’t believe you got one over on him, but there’s no anger in it — just that big-brother okay, show me you’re serious energy. The only person in the room who looks horrified is Spencer, who’s clearly just trying to cope with the fact he accidentally revealed your relationship in maybe the stupidest way possible.
You take a breath, feel your pulse in your throat, and then — because you’re not going to let all of your control over this situation be ripped out of your hands — you say:
“Congrats everyone, you cracked the code. Yes. Reid and I are together.”
Garcia explodes.
“MYSTERY GIRL IS YOU,” she shrieks, half out of her chair. “It’s been you this ENTIRE time. Oh my GOD. I made a board! I made assumptions! I said cupcakes and cardigans when in reality, Mystery Girl was right in front of me in boots and a leather jacket and—”
“Garcia,” Hotch warns.
JJ’s earnest expression is the first thing that cuts through the chaos. “This makes so much sense,” she says.
“Yeah,” Emily agrees. “The second you say it out loud, it’s like— of course. How did we miss that?”
Morgan sits back, still staring between you and Spencer like he’s recalibrating. Then he lets out a laugh — half disbelief, half delight. “Man,” he chuckles, shaking his head, “I thought you were cuddled up with a librarian or something. Meanwhile you’re out here dating the most terrifying Greenaway sister,” he says, then winks at you like he’s trying to make sure you know he means it as a compliment.
You lift your chin. “Say that again and I’ll throw this pie at you.”
Morgan grins, hands up. “See? Exactly what I mean.”
Rossi sips his wine with a chuckle. “About time you bozos figured it out.”
Garcia whirls on him. “You KNEW?!”
Rossi’s mouth quirks. “What can I say, I’m good at my job.”
Hotch sets his fork down with the resigned patience of a man who has filled out a lot of paperwork on this exact subject already. “I’ve also been aware for some time,” he says evenly.
Garcia makes a noise that sounds like she’s dying. “BOTH of you knew?!”
Spencer clears his throat, still pink, still looking like he wants to apologize to you in six different languages. His eyes don’t leave your face.
Garcia’s hands clap together like she’s calling court to order. “O.M.G. never stood for Operation Mystery Girl,” she announces, breathless with triumph. “It stood for OH MY GREENAWAY all along.”
JJ’s gaze meets yours. “For what it’s worth,” she says, "I'm really happy that Mystery Girl is you.”
Emily lifts her glass in a small toast. “Me as well,” she adds. “This is good. This is really, really good.”
Morgan’s grin softens into something fond and protective. “As long as you’re both happy and nobody’s getting hurt,” he says, “I’m happy for you. Both of you.”
Garcia’s voice goes thick, emotional, and she tries to bulldoze right through it with dramatics. “I’m so happy,” she declares. “I’m also a bit devastated I wasn’t included in the secret circle of knowing earlier, but mostly I’m happy because you two are…” She gestures wildly. “You’re you. And it’s perfect.”
Something in your chest steadies instead of cracks.
“Okay,” you say, exhaling. “Cool. Great. Everybody get it out of their system?”
Garcia points at your pie plate, still half-disassembled. “Not even close. I’m sorry,” she gasps, “but I can’t get over that THIS is what did it.”
You deadpan. “My beef with pie is never-ending.”
Rossi claps once, satisfied. “Alright. Now that the children have finished screaming, eat your dang dessert.”
Laughter rolls around the room again, warmer now, less sharp.
Under the table, Spencer’s shoe nudges yours.
You nudge back.
And when you finally escape an hour later, the night air is cold and quiet, and Spencer grips the steering wheel like he’s trying to drive his guilt into the pavement.
You watch him from the passenger seat, heart weirdly calm.
He doesn’t say much on the drive. Neither do you. The secret is out, the world didn’t end, and for now, that’s enough.
—
Back at Spencer’s apartment, the quiet hits you like a soft wall.
No Garcia shrieking. No Morgan cackling. Just the click of the lock, the hush of the hallway outside, and Spencer standing there with his keys still in his hand.
“You okay?” you ask, toeing your shoes off.
Spencer exhales — sharp, like he’s been holding it since the pie incident — and sets his keys down with exaggerated care. Then he turns to you, eyes wide in that way they get when he’s trying not to catastrophize and failing.
“I’m sorry,” he says quietly.
You blink. “You don’t need to be.”
He shakes his head. “But I am. I’m so sorry. For all of it. For telling them the fruit thing. I didn’t realize I was outing us. I—I didn’t know there was going to be pie.”
“I gathered that,” you say.
He steps closer, hands hovering at his sides like he wants to touch you but doesn’t want to assume it’d be welcome.
“I shouldn’t have said anything,” he continues, words tumbling now that the gate’s open. “It was stupid. I thought giving them a hyper-specific detail would give them something to fixate on and shut them up, and that one seemed harmless enough, but then I saw the pie and I—” He swallows. “I really did try to warn you.”
“You did,” you say, leaning back against the wall. “You were practically doing Morse code against my ankle.”
“I panicked,” he admits, cheeks flushing. “And then it all happened so fast and you looked—” He stops, eyes flicking over your face like he’s searching for hurt. “I’m sorry. I didn’t mean to put you on the spot. I know you hate being… perceived.”
He takes one more step. You can feel his warmth now, close enough that it seeps into you.
“I keep thinking about the other day,” he says quietly. “How scared you were for them to find out.” His throat bobs. “And then I was the one who—who basically handed them our secret on a silver platter.”
You tilt your head. “On a pie platter, actually.”
He looks pained. “Please don’t make jokes right now.”
“Spencer,” you say seriously. “I’m not mad at you.”
He lets out a breath, but it’s not quite relief yet. He’s still braced for impact.
“And I’m not mad that they know,” you add, watching him closely. “I mean, I’m a little embarrassed that my downfall was pie of all things, but—”
His mouth finally lifts, small and uncertain.
“But,” you repeat, “it’s okay. I’m fine, really.”
You push off the wall and close the space remaining between you, because you’re tired of him hovering at the edge of you and want him to feel how not-mad you are.
His hands find your waist the second you’re close enough, careful at first, then firmer when you lean in like you belong there.
“Are you sure?” he whispers.
You nod. “I’m sure.”
“Because you could—” He swallows. “You could decide this is too much. Too exposed. And I wouldn’t blame you, but I’d…” His voice cracks just slightly. “I’d miss you.”
Something in your chest goes tight and hot.
You slide your hands up his arms, feel the muscle under his sleeves, the faint tremor he’s trying his best to hide. You clasp your fingers behind his neck and pull him down until his forehead nearly brushes yours.
“I’m not going anywhere,” you murmur.
His eyes flutter shut for half a second, like the words physically steady him.
“You’re not?”
“No,” you say, and you let yourself mean it. “I told you, I’m not mad. I’m not running. The worst thing that happened tonight is that our coworkers found out I have psychopathic dessert habits.”
He huffs a laugh.
“Besides,” you add, because you can’t help it, “you looked kinda hot when you were trying to telepathically get me to eat my pie like a normal person.”
His eyes open, startled. “I— what?”
“You did,” you insist, deadly serious. “Somehow, panic is a good look on you. Big fan.”
His cheeks go pink, but now it’s in a good way.
“You’re unbelievable,” he murmurs, shaking his head like he’s trying to hide the smile.
“And you,” you say, sliding your thumbs along his jaw, “are catastrophizing.”
“I know,” he admits. “I just… I care about you.”
The words hang there, heavy and honest and dangerously close to a bigger truth, but you don’t let it scare you. Not tonight.
You kiss him instead.
It’s slow at first — soft, testing — like you’re proving something to him with your mouth: I’m here. I’m fine. Then it deepens, because Spencer never stays soft for long once you give him permission. His hands tighten at your waist, pulling you in until there’s no space left to misunderstand.
His mouth is warm, familiar, and still somehow new every time. You feel him exhale against you, a quiet sound that sinks into your skin.
When you pull back, he looks at you again and cups your cheek like you’re something precious.
“I’m glad you’re okay with this,” he says.
“I’m okay,” you say, and kiss the corner of his mouth. “I’m… actually kind of relieved.”
His brow furrows. “Relieved?”
You roll your eyes, because you refuse to be poetic about it. “Yeah. It’s out, and they didn’t—” You falter, just a flicker. “They didn’t look at you like you were making a mistake.”
His expression softens.
“No,” he agrees. “They didn’t. I told you they wouldn’t.”
You nod once. “And you were right. So, I’m good.”
“Good,” he echoes, but his thumb keeps stroking your cheek like he doesn’t want to let the moment go.
Your gaze drops to his mouth again. His eyes follow it, and his breathing changes — subtle, but you know him by heart now.
You smirk and lean in closer until your lips are brushing with every breath. “And hey, now that the team knows, we don’t have to pretend we’re not together every second of the day anymore,” you tease.
His voice goes a little rough. “We still shouldn’t, uh, do anything at work, you know.”
“Obviously,” you say, like you’re offended he even suggested it. “But we’re not at work right now, are we?”
He shudders softly as his hands slide from your waist to your lower back, drawing you closer like he’s been waiting all night to do this without consequence.
“No,” he murmurs. “We’re not.”
You kiss him again, deeper this time. He gives in completely, following your lead with that sweet, earnest hunger that always makes you feel a little wicked and a little adored at the same time.
When you finally break apart, you’re both breathing differently. He rests his forehead against yours, eyes half-lidded.
“I’m still sorry,” he whispers.
“Don’t be,” you say. “It’ll make a good story someday.”
His throat works. His hands tighten on you like he needs the confirmation in his bones.
You press your mouth to his once more, slow and sure, just to make the point stick.
“Case closed,” you murmur against his lips.
Spencer’s smile turns soft and helpless. “Yeah,” he whispers. “Mystery solved.”
