**“**
The hallway outside the mess hall smells like frosting. Not the sterile kind replicated in bulk, but the real deal. Butter, vanilla, something warm that reminds Jim of birthdays back home, back when his mom still tried. He leans against the wall, arms crossed, watching crewmen pass by without a clue that there’s a whole party waiting on the other side of the door.
He checks the time. Scotty’s due in five minutes.
The lights are dimmed just enough to make the decorations pop. There’s a giant banner reading **“Happy Birthday, Scotty!”** in bright red letters, hung just slightly crooked. Jim had let Chekov handle that part. He didn’t have the heart to correct the kid’s enthusiasm.
Inside, people are whispering and snickering, hiding behind tables and pillars, trying to stay still. It’s not exactly the stealthiest group, but the effort counts.
Jim’s not really thinking about the cake or the surprise anymore. His eyes drift toward the corner where Spock and McCoy are pretending not to argue. Again.
McCoy’s arms are moving too much, his face tense but quiet. Spock is still, barely blinking, like the words bouncing off him don’t land. But they do. Jim knows they do. He can see it in the twitch of Spock’s jaw, the slight narrowing of his eyes.
They’re always circling each other, never quite closing the gap. Jim used to think it was just hate. Then he thought it was maybe friendship. Lately, he doesn’t know what to think. Only that watching them is like watching fire try to make peace with ice.
And he’s standing right in the middle.
The thought makes his chest feel tight. He shakes it off.
The door whooshes open, and Nyota slips out. “He’s on his way,” she whispers, eyes sparkling. “We’ve got two minutes.”
Jim straightens up, nods. “Positions, everyone.”
He feels ridiculous saying it, like they’re gearing up for battle instead of a birthday. But the crew scrambles, stifling laughter. Even Spock moves behind a pillar, though he gives Jim that look. The one that says, **This is entirely illogical, but I’m doing it anyway because of you.**
Jim feels a flicker of warmth behind his ribs.
McCoy ends up next to him, brushing close. Too close. Jim’s suddenly aware of the way Bones smells—like soap and whiskey and something dry and familiar. His arm presses against Jim’s, steady, grounding. They don’t look at each other. They don’t have to.
The door opens again.
“Surprise!”
Scotty jumps a full foot, drops the datapad he’s carrying, and clutches his chest. “Bloody hell!”
Everyone laughs, loud and delighted. The lights come up. Scotty blinks into the brightness, his face going red in that way only he can. “You bastards,” he says with a grin. “You beautiful, sneaky bastards.”
The crew swarms him with hugs and claps on the back. Music starts playing—something fast and ridiculous. Someone passes out drinks. Someone else lights the candles on the cake.
Jim hangs back for a second, watching it all unfold.
Scotty’s laughing like a maniac, already halfway through a drink. Chekov’s dancing with two ensigns. Sulu’s telling some story too loud. And Spock and McCoy—Spock is at the table now, calmly slicing the cake with geometric precision, while Bones hovers beside him, pretending not to supervise.
Jim feels the corners of his mouth tug upward. This—this is why he does it. The ship, the crew, the weird little family they’ve built. Even the chaos feels like home.
He walks over to the table and picks up a piece of cake.
“You planning on eating that or just staring at it?” Bones says without looking at him.
“I’m appreciating the craftsmanship.”
“It’s yellow cake. With chocolate frosting.”
“It’s a classic.”
Bones snorts and leans closer. “You okay, Jim?”
The question catches him off guard. He turns toward Bones, opens his mouth to answer, then notices how close they are. Too close. Again.
“Yeah,” he says. “Just… soaking it in.”
McCoy nods like he doesn’t believe him but isn’t going to press.
Spock slides another plate across the table. “Captain. I believe you favor corner pieces.”
Jim blinks. “How do you—?”
“You consistently select them at communal meals involving cake.”
That shouldn’t make Jim’s heart skip, but it does.
McCoy rolls his eyes. “Spock, you keep track of his cake preferences?”
Spock looks at him evenly. “I keep track of everyone’s preferences. Including yours, Doctor.”
There’s a pause.
Jim eats his cake, pretending not to feel the heat crawling up his neck.
The party keeps going for hours. People drink too much, dance too hard, and laugh too loud. Eventually, the crowd thins. Scotty disappears with a bottle under one arm and two engineers under the other. Sulu and Chekov leave together, still arguing about card rules.
Jim stays behind to clean up. He says it’s because he wants to, but really, he just needs a few minutes to himself.
He starts stacking cups into a trash bin when a quiet voice interrupts him.
“You should let the cleaning crew handle this,” Spock says.
Jim glances over. Spock stands near the table, hands behind his back, watching him.
“I wanted to,” Jim says. “Helps me unwind.”
Spock nods once but doesn’t leave.
“Where’s Bones?” Jim asks, trying to sound casual.
“He returned to his quarters. He claimed he was 'done with this damn circus’.”
Jim chuckles. “That sounds about right.”
Spock steps closer. Not enough to invade space. Just enough to make Jim’s heart notice.
“You were unusually quiet tonight,” Spock says.
“Was I?”
“You often dominate social gatherings.”
Jim laughs once. “Yeah, well. Didn’t want to steal the spotlight from the birthday boy.”
“That is not your usual concern.”
Jim stops stacking cups.
Spock watches him carefully, almost too carefully.
Jim leans against the table. “You ever think about what we’re doing?”
“In what context?”
“This. All of this. Starfleet, the Enterprise, birthdays in space.”
“I consider it regularly.”
“And?”
Spock takes a moment before answering. “It is… unexpected. The connections we’ve made. The emotional depth of our crew. The ways in which this assignment deviates from standard protocol.”
Jim smiles faintly. “You mean the fact that we’re all hopelessly entangled?”
“That is one way to describe it.”
He exhales slowly, the weight of the evening catching up with him. The laughter, the lights, the longing.
“I don’t know what to do anymore,” he admits.
Spock tilts his head. “Regarding?”
Jim shakes his head. “You and Bones.”
Spock doesn’t move, but something shifts behind his eyes. “I see.”
Jim looks down at the table. His fingers trace a ring of condensation. “You two… you drive each other crazy. But it’s more than that. I see the way you look at him.”
“And the way you look at us,” Spock says quietly.
Jim looks up. Spock’s eyes are dark, steady, unwavering.
“It’s not fair,” Jim says. “Wanting both of you.”
“No,” Spock agrees. “But fairness is not a prerequisite for feeling.”
Jim feels like the floor tilts under him a little.
“I love him,” he says. “And I love you. And I don’t know how to stop.”
Spock breathes in slowly, controlled. “I do not wish for you to stop.”
Silence stretches between them.
Jim’s pulse hammers in his throat.
Then Spock steps closer, close enough that Jim can feel the heat of him, the tension in the air like a wire pulled too tight.
“I believe,” Spock says, voice barely audible, “that the doctor feels the same.”
Jim swallows. “Then why do we keep pretending we don’t?”
“Fear,” Spock says. “Of damage. Of change. Of pain.”
Jim lets out a breath. “I’m already in pain.”
Something flickers in Spock’s expression. Not quite sympathy. More like recognition.
Jim reaches out, fingers brushing Spock’s wrist. The contact is electric, grounding, terrifying.
“Come to my quarters,” he says, voice rough. “Both of you.”
Spock nods once. No hesitation.
“I will inform the doctor.”
Jim watches him leave, his chest aching in every direction.
**“** **“**
Later, in his quarters, Jim sits on the edge of his bed, heart pounding.
He hears the chime at his door. When it opens, McCoy steps in first, hair messy, eyes tired. Then Spock behind him, calm and unreadable.
Nobody speaks at first.
Then Bones says, “You better know what you’re doing, Jim.”
“I don’t,” Jim says honestly. “But I want to try.”
McCoy looks at Spock. “You sure about this?”
“I am,” Spock says.
Jim stands. His hands tremble a little. He doesn’t hide it.
“I don’t want this to be a secret anymore,” he says. “I’m tired of waiting for things to fall apart. I want to hold onto something before it does.”
McCoy steps closer. Spock does too. They meet in the middle, all three of them within arm’s reach, hearts beating loud in the silence.
Then McCoy lifts a hand and cups Jim’s cheek. Spock’s fingers brush his wrist.
And for a moment, there’s no war, no rank, no space between the stars.
Only this. Only them.
