a/n: a little something for my fellow Dexter fans
The sun was beating down on the field, and you were already starting to regret not grabbing your water bottle. Your team of elementary schoolers was bouncing around you like they’d been given espresso shots instead of juice boxes, their energy sky-high for the last day of camp. And who could blame them? Today was the big showdown – the ultimate battle between Team A and Team B. Your team, obviously, was Team A which, you reminded them every chance you got, was the first letter of the alphabet for a reason.
You scanned the field, making sure everyone had their places, when you saw a stray kickball, sitting just past the starting line. You sighed. As much as you loved your kids, “picking up after themselves” was an elusive skill for most of them. You told them to hold tight for a second and jogged over to retrieve it.
Just as you were about to grab the ball, you saw Dexter walking up beside you, giving you that unreadable look, as usual. You smirked before he even had a chance to speak.
“Well, if it isn’t the illustrious Team B leader himself,” you said, bending down to pick up the ball. “Here to observe greatness in action?” you asked with a proud smile on your face.
Dexter didn’t miss a beat, casually handing you a bottle of water and raising an eyebrow. “Greatness? I think you’re setting them up for disappointment.”
“Oh, really?” you grinned, turning to face him as you spun the ball between your pointer fingers before resting it on your hip and taking the water. “Coming from the guy whose team spent ten minutes building an egg drop contraption that looked like a rejected spaceship model?”
Dexter’s face didn’t change, but you could see the spark of amusement in his eyes. He took the smallest step forward, as if to intimidate you. “That ‘rejected spaceship model’ actually worked, if you remember correctly,” he replied smoothly. “Unlike some teams’ eggs, which ended up looking like scrambled breakfast.”
He was right, of course. His egg drop design looked like it had come from an old sci-fi movie, a quirky contraption with beams, paddings, and an absurd amount of plastic wrap. You had no idea where he got all that, either way, it worked.
It wasn’t even surprising; Dexter had always taken unexpected routes to solve problems. His mind just worked differently. You knew he had a wild imagination; you could tell when he’d shown you some of his high school lab projects, each one stranger and more intricate than the last, and always with that unmistakable Dexter touch that landed him at the top of the class every time. Even now in college, he was still securing the highest grades, beating out students who had twice the resources and flashy internships.
Honestly, Dexter was probably the smartest person you knew, and being able to go toe-to-toe with him here at camp wasn’t just a thrill – it was an honor.
It was part of what made this science camp so special. It wasn’t just some neighborhood summer program; it was hosted by your college’s STEM department, high-level experience for kids that were intrigued by the world of science. Or even those who were just curious about the basic laws of nature ruling our world. The camp was selective about who it chose to lead, and the program heads always made sure to match top students with the best opportunities.
You knew Dexter had signed up for the challenge partly because he’d mentioned wanting to “quit an old habit” and keep himself busy during summer. He hadn’t told you much beyond that – just something vague about needing to break a pattern, occupy his time in a way that felt constructive. This camp, with its structure, routine and purpose was a way for him to do that.
And then, there was the way he was around kids. Despite his reserved nature, he seemed at ease with them, almost unguarded. Dexter seemed different, and only a few people got to experience this side of him. He once joked to you that kids’ brains were underdeveloped enough that he didn’t have to fake emotions or second-guess his reactions around them.
But right now, there was a different Dexter in front of you – not a soft Dexter, not a reserved Dexter. There was a smirking, overly confident camp leader Dexter who thought he could take you down. You hated that he felt comfortable enough to be this cocky towards you. So no, you weren’t about to let your admiration show. You'd have enough time to let yourself sneak a few appreciative glances at him when he wasn’t looking, but right here, with the competition about to continue? You weren’t going to let him talk you down.
You stepped closer too, having to crane your neck a little to keep eye contact. “Don’t worry. My team and I have an actual strategy. Not just a bunch of science facts thrown together like a five-paragraph essay.”
He snorted, his eyebrows rising. “It’s a science camp. Facts are kind of the point. Your strategy is taking the name Team A and thinking that it will actually secure you the first place.”
You scoffed and turned around, walking towards your team and Dexter was quick to follow you.
“First letter, first place. It’s called manifestation. It’s like destiny. We’re literally setting ourselves up for success from the start.”
He shook his head with a little laugh. “You realize it’s just a letter, right? It doesn’t have, like, mystical powers or anything.”
You couldn’t help but cackle, his words making you stop again and some of the smaller heads turn in your direction, silently watching the respected leaders of the science camp bicker. He was unbelievable.
“Please, you’re just pissed that I called it first.”
Despite Dexter being stoic and unpopular among his peers, he was good with kids, and you were aware of that. He was a lab geek to everyone, even his fellow students who majored in science too -- everyone was supposed to be a lab geek! - But most didn’t know that he was actually very creative. You knew that and this was just bitterness talking.
“It’s the first thing people see, the first letter people think of. It exudes victory. Doesn’t Team B just sound… second-rate by comparison?”
He gave you a deadpan look, which only made you want to argue for your team more.
“Team B,” he said, with an exaggeratedly thoughtful expression, “actually stands for best. Maybe even better. I wouldn’t be so quick to assume we’re coming in second.”
You shook your head and bit your cheek, contemplating your next words. You brought the ball that was on your hip to his chest, slightly pushing him with it, but he didn’t budge. He just took it as he waited for your next remark.
“My Team A kids are about to wipe the floor with your Team Better.”
He chuckled and threw the ball into the air before catching it. “We’ll see about that,” he said, eyes glinting with that calm confidence that always got under your skin.
You turned to your group again, arms stretched for emphasis. “See? He’s already trying to play mind games because he knows Team A is unstoppable!”
The kids cheered, and you looked back at Dexter, who was fighting a grin.
“Careful,” he said, “I’d hate to see you go down after all that talk.”
You leaned closer, and you saw his eyelids flutter, finally a sign of weakness.
“And I’d hate to see you hand over those first-place prizes with that smug look wiped off your face.”
You found yourselves in a silent, smirking standoff. His lips curved ever so slightly, daring you to say something more. The corners of your mouth tugged upward in response. You weren't backing down, and neither was he, testing each other, seeing who would blink first. You let your eyes drop just briefly, enough to catch the flutter of his lashes, but a voice from behind cut through the haze, breaking the moment like a splash of cold water.
“You’re going down, Mr. Dexter!”
You both turned toward your team, seeing one of the more spirited girls in your group, Sarah, giving Dexter a withering stare.
You crossed your arms, looking at Dexter. “See? You’ve gotta inspire these kids, Dexter. Get them excited! Pumped!” you slapped his triceps as if to emphasize your point, and he side-eyed you. “No wonder Team B’s lagging behind,” you switched your expression to an exaggerated pity, sighing and shaking your head.
“Alright,” he murmured, your trash talking finally getting to him. “I gotta go. I have to tell my team about Team A’s lack of structural integrity and how we’re going to crush them in the obstacle course.”
You gave him a taunting smile, before he walked away.
“And thanks for the water!” you lifted the bottle in the air and he turned, nodding at you with a genuine smile. Before he headed to his kids, he made a stop where your team was hanging. Despite him being the leader of the opposing team, instead of being intimidated or intimidating, the kids smiled at him, some of them running up to him and showing him a bug they just found in the grass.
You watched him stop right in front of Sarah, crouching down to her eye level with an inquisitive look. “Did I just hear you say I’m going down?”
She shifted her feet, but held her ground, her cheeks red. Kind of like you when you first met him. “Well…yeah!” she crossed her arms, mustering her bravest face. Honestly, you couldn’t be prouder. “We’re Team A, so we’re winning this competition – duh! Plus, we have Ms. YN, and you don’t!”
“Point taken, Sarah,” he said with a chuckle. “I think you’re ready to start a motivational business someday.” The kids giggled, including Sarah who had a proud smile on her face. Dexter raised his eyebrows expectantly, offering his hand to Sarah. “May the best team win, then.”
She shook his hand and with one last look to you, he left. You made your way to your team and gave Sarah and some other kids high-five.
“Did you see his face, Ms. YN? He knows we’re gonna win!”
You laughed, nodding. “Oh, he definitely knows. Let’s make sure he remembers it.”
You sat in your chair and watched your kids, dressed in their teams’ tie-dyed orange t-shirts as some of them were clutching their juice boxes trying the slurp up the last drop, some were still playing with their DIY space shuttles from the NASA day, and some were playing tag or patty cake with each other.
It had been a great few weeks and you couldn't believe the camp was almost over. It was always hard for you to say goodbye. Some of the kids came back every year and you were happy to see their faces. Of course, there is a few bad eggs, but the overall experience was always amazing. And even though it might have not seemed that way, you enjoyed sharing that experience with Dexter, who was one of the smartest people you knew.
You turned around, looking in the direction of his team, watching him sitting on the ground, stealing Franklin’s hat, exposing the boy’s ruffled hair as Dexter put it on his own head, the hat obviously too small for him. Franklin tried to get it back, reaching for it, but Dexter quickly snatched it away and held it out of his reach, making the boy crawl over him as he laughed hysterically.
Your heart fluttered at the sight, but you shook it off, turning back to your team and making a regular head count.
The rest of the afternoon flew by as the competition heated up. Your team was cheering like maniacs after each round, pumping each other up with a team spirit that only a summer camp could create.
Next up was a chemistry challenge, where each team had to mix different chemicals to create a specific color in their beakers. Your team surged ahead, mixing the combination quickly, while Dexter’s team carefully measured out each drop.
“Come on, Team A! Don’t let Team B show us up!” you encouraged, but your team’s rush and Dexter’s team’s focus worked in his favor, adding a few point to his part of the scoreboard.
As the afternoon wore on, the two groups moved from one challenge to the next, each victory and loss met with cheers and groans. Finally, the last event arrived: the biology obstacle course. The campers were buzzing with excitement, and you could barely contain your grin as you glanced across the field at Dexter. The score was pretty much tied, and it all came down to this.
“Alright, A’s,” you said, crouching down to your group’s level. “This is it. Remember to have fun, and let’s give it everything we’ve got.”
The obstacle course was a test of agility and knowledge. Each camper had to climb through a “jungle” of hanging ropes, identify plastic animal replicas hidden among the trees, and finish by sprinting to the finish line with a “baby bird” (a rubber ball) in a spoon.
Your team went first, charging through the course with surprising speed. Dexter was impressed but kept his expression neutral. His campers were determined to outdo them, each one putting in their best effort as they charged through the course, cheered on by Dexter’s calm, steady encouragement.
When the final camper crossed the finish line, you and Dexter called your teams together to tally up the points. The competition had been so close that neither group was sure who had won.
“Alright,” Dexter said, reading off the scorecard. “And the winner is…” he paused, dramatically prolonging the suspense, while you shot him an exaggerated look of impatience.
“Team A!” he announced, unable to keep from smiling as your team erupted in cheers. He felt bad for his team, but a flicker of pride rose in his chest as he watched you celebrate with your kids, hugging a few of the campers. You shot Dexter a smug, triumphant look, mouthing “I told you so.”
The losing team received consolation prizes – a handful of science-themed chocolate bars and some novelty key chains shaped like tiny beakers and DNA strands. The kids took it all in stride, laughing and goofing off as they filed back to their cabins, waving at you and Dexter as they disappeared down the paths.
You and Dexter began gathering up the supplies left over from the relay race. Every so often, you’d bump shoulders or catch each other’s eyes and share a smile.
As the last of the campers drifted out of view, you took a long breath, letting it out slowly as the day’s exhaustion sank into your muscles. You stretched your arms overhead, feeling that familiar soreness, and smiled as you glanced over at him.
“Guess that makes me the science camp champion, huh?”
Dexter chuckled softly, his eyes glinting with amusement. “For this year, maybe. Next year, though, don’t get too comfortable.”
You laughed, feeling a spark of joy as you realized, yes, you would look forward to next year – another summer with him, another chance to see this side of him. You were alone by now, perched on the steps of the main cabin where the camp leaders, cooks, and cleaners stayed during camp sessions. You leaned back, savoring the quiet, the fading light of the day casting a soft glow over the campgrounds.
Dexter sat down beside you, resting his elbows on his knees as he gazed out at the now-quiet field, his Adam’s apple bobbing as he swallowed hard. After a moment, you scooted closer, letting your chin dig into his shoulder. Gently, you threaded your arm through his, reaching for his hand and giving it a small squeeze. He looked down, his expression softening as he turned to you, and suddenly you were so close your noses were almost touching, the fading sunlight casting shadows over his features and catching on the ginger stubble along his jawline.
“Same time, same place?” you murmured, your voice low and quiet.
Dexter didn’t answer – not with words, anyway. Instead, he lifted a hand to brush away the baby hair from your forehead before closing the space between you, his lips meeting yours in a soft, lingering kiss.
You always made his heart beat so fast, he didn’t know how it hadn't burst already. You were one of two things that made him feel this way and it was a perfect balance of light and darkness.
His stubble scratched lightly against your skin, a slight irritation that you secretly loved. It made you smile against his lips, feeling a familiar thrill rush through you.
You remember teasing him about it early on in your relationship, only for him to take it too literally and show up the next day, clean-shaven. You’d laughed, explaining that it was just a joke, and that you loved his rough edges. It made you love him more, it was just so Dexter.
Since then, he’d kept his natural look, but sometimes, you’d see that flicker of hesitation, trying to understand the meaning behind your words and actions. It reminded you how hard he tried to learn the language of affection, your love language, and you tried to learn and understand his. It put you into perfect synchrony.
He leaned into the kiss with more force before pulling away and letting his forehead rest against yours, noses brushing as he lingered there, his hand still holding yours as you drew circles on his skin with your thumb.
“Wouldn’t miss it,” he replied, his usual calm and stoic replaced by a rare warmth as he looked at you.
You smiled and kissed his shoulder before resting your head against it, letting your eyes close for just a moment.
“It’s so quiet.” you sighed, enjoying the peaceful moment. That’s something you'd missed. Even though you loved the camp, you weren't really a fan of chaos, and this? Having the moment to breathe in the warm scent of pine trees, to hear the birds singing and crickets chirping and to be in Dexter’s embrace is like a reward.
“Funny you’d say that, considering how much noise you make.” He glanced down at you, raising his eyebrows. “Half the chaos around here has been you cheering your team to victory.”
You scoffed, too tired to put up a fight this time. “I’m just an enthusiastic leader.”
“Oh, I know,” he said, a hint of smirk tugging at the corner of his mouth. “You’re definitely enthusiastic. I’m pretty sure you broke the sound barrier.”
You poked him in the ribs, and he genuinely laughed. A sound that you appreciated greatly, because you were one of the few people that got to hear it. As his laughter faded, he leaned in and pressed his lips softly to the crown of your head.
You watched the sun dip lower, your heart full as you let yourself drift into the soft, steady rhythm of his breathing.
