Can verbs be invented? I want to tell you one: I sky you, so my wings spread wide to love you without measure.
– Frida Kahlo
The argument starts like most of theirs: small, sharp, and stupid. Spock brings up the captain’s workout routine during a routine exam. McCoy hears judgment in a sentence that never uses the word. Spock offers a statistic; McCoy snorts and crosses his arms like he’s fortifying a perimeter.
“Your concern is noted, Mr. Spock,” McCoy says, dry enough to crack. “Maybe you can post a schedule on the mess hall wall: When To Breathe, According To Vulcan Science.”
“I do not recall commenting on respiration,” Spock replies, hands behind his back, posture perfect, eyes steady. His voice stays even. Something in his jaw tightens. “I commented that his cortisol levels indicate—”
“Indicate that he’s a human captain under stress,” McCoy cuts in. “Newsflash. We’re all tired. You’re just the only one who treats fatigue like a moral failing.”
Spock blinks, slow and offended in the Vulcan way. The biobed hums. The office door remains open to sickbay’s quiet bustle; nurses pass like ghosts, the soft clink of instruments keeping time. McCoy turns toward his office, tosses a “You can leave your concerns with Nurse Chapel,” over his shoulder, and walks away.
Spock follows. The door shuts behind them with a whisper that carries weight. McCoy leans on his desk and rubs his eyes. His hand shakes, barely. He’s had two cups of coffee and a raid of adrenaline in the last hour. Spock notices. Spock notices everything.
“You are deflecting,” Spock says.
“I’m triaging annoying,” McCoy says, then sighs when Spock’s eyebrow rises. “Fine. Sit. Or stand like a coat rack, whatever suits your people.”
Spock does not sit. He steps closer instead. The office lights smear a thin gloss over his dark hair. He looks like a sculpture built to carry alarm bells. “You frequently accuse me of failing to account for human variables. You are correct. I am attempting to account for them now.”
McCoy’s laugh is short and tired. “By storming into my office to scold me about Jim?”
“By acknowledging that I am… concerned.” The word lands awkwardly, nearly foreign. Spock straightens another millimeter. “I am concerned for the captain. And for you.”
The room shrinks. McCoy stares, then shakes his head. “You always choose the worst moment to be almost human.”
Spock takes another step. McCoy’s hip bumps the desk. Spock’s hands are still clasped behind him, like he’s keeping them there by force. His pupils look darker than usual. “Doctor.”
“What,” McCoy says, throat rough.
“You are trembling.”
“Give me a minute and I’ll tremble louder.”
“I am not attempting to provoke you,” Spock says, softer now. “I am attempting to tell you that I cannot continue this pattern.” His gaze drops to McCoy’s mouth and jumps back up. “I am failing to maintain equilibrium. Your presence contributes to this failure.”
McCoy’s breath catches on a laugh that isn’t a laugh. “You’re blaming me for your equilibrium?”
“I am crediting you,” Spock says. His voice darkens, a lower register that slides under McCoy’s ribs and lives there. “It is intolerable.”
“Then go,” McCoy says, but he doesn’t move. He can’t decide which part of him is louder—the part that wants the fight or the part that wants the thing under the fight. Heat flickers up his neck. “Door’s right there.”
Spock stands so close the edge of his jacket brushes McCoy’s thigh. His hands finally abandon the safe line behind his back. They hover, uncertain, then plant on the desk on either side of McCoy’s hips. The desk digs into McCoy’s spine. Spock’s scent—clean, faint spice from Vulcan soap—fills the space like a promise broken open.
“This is the door I cannot breach,” Spock says quietly. “I approach and you meet me with arguments. I retreat and you pursue me with mockery. I am… outmaneuvered.”
McCoy’s mouth goes dry. “So you came in here to surrender?”
“I came in here to stop pretending I do not want to touch you,” Spock says.
The sentence strips the air down to light. McCoy blinks. The ship’s hum sinks deeper, a bass note under his skin. Spock is close enough that McCoy can see the small tension in his cheek, the exact shape of self-control bending to a breath.
“You’re going to say it like that,” McCoy manages. “No poetry, no warning.”
“Is there poetry that would satisfy a physician whose blood pressure is elevated and whose hands—” Spock looks down; McCoy realizes his fingers have curled into Spock’s jacket. He doesn’t remember grabbing. He doesn’t remember deciding to move at all. “Whose hands are already holding on.”
McCoy swears under his breath. The laugh comes back, shaky and bright. He wants to push Spock, just to see if he’ll push back. He wants to be pushed and held at the same time. He wants a thousand impossible things and they all land on the same point: the two inches between his mouth and Spock’s.
“You don’t lose control,” McCoy says, a last defense.
“Incorrect,” Spock says, and the word breaks like a string pulled too tight.
He moves. The kiss arrives like a collision and a cure. McCoy’s head hits the wall with a dull thud, shock flaring, then dissolving into heat. Spock’s mouth is hot and decisive, all that restraint converted into purpose. McCoy opens to it instantly. His hands climb, fist in lapel and then flatten to drag Spock closer. The office disappears. The argument melts down into breath and pressure and the low sound Spock makes when McCoy bites his lower lip.
McCoy feels pinned, contained, and cherished at once. Spock’s palm finds his cheek, fingers spread like a measurement taken in reverence. He kisses like an equation that finally balances if he just dares to carry the one. The impact, the heat, the way Spock’s breath stutters—every line of it lives in McCoy’s chest now, bright and reckless.
He breaks for air. “Spock,” he says, less a name than a surrender. “God.”
“Leonard,” Spock says, voice wrecked and careful. He pulls back half an inch, checks McCoy’s eyes with an intensity that disarms. “Consent.”
“Hell yes,” McCoy says, laughing on the inhale. “Keep going.”
Spock does. The next kiss is slower, deeper, the kind that unthreads anger and stitches something steadier in its place. McCoy’s hands slip under the jacket and find heat under uniform fabric. Spock’s shoulders are stone and warmth together; a tremor runs through them when McCoy thumbs along his collarbone.
His mouth finds Spock’s jaw, the spot where pulse hides under smooth control. He kisses there, lets his teeth scrape the line lightly, and feels Spock exhale like a door swinging open. “You’re impossible,” McCoy murmurs against skin.
“I am statistically unlikely,” Spock says, and shudders when McCoy kisses that spot again. His hands move at last—one braced on the desk, the other sliding down McCoy’s side to his waist. The grip is firm enough to anchor, gentle enough to ask a second question.
McCoy answers by dragging him closer until hip meets hip. Electricity ladders through him. He wants to laugh and cuss and beg in the same breath. “You waited too damn long,” he says.
“I was not certain you would welcome—”
“Spock,” McCoy interrupts, cupping his face. “Look at me.”
Spock obeys. His eyes are dark, pupils blown, composure rearranged into something raw and elegant. McCoy sees the man who holds entire star charts in his head. He sees the man who stayed by his biobed through six hours of fever, silent and relentless. He sees want, and he sees relief.
“Welcome home,” McCoy whispers, and kisses him like he means it.
Spock makes a sound that could be a laugh and could be a prayer. He leans in and the kiss turns hungry again, the kind that leaves a heat-shadow along McCoy’s spine. The wall is cool at his back. Spock’s chest is warm and rising faster now. Somewhere outside, a tray clatters and a nurse murmurs, but the office might be an asteroid spinning alone.
McCoy pulls him into a hug that isn’t careful at all. He squeezes hard enough to feel the shape of Spock’s ribs under layers of uniform and discipline. Spock stiffens, then melts, a subtle drop in tension that feels like watching a storm pass in time-lapse. His chin rests against McCoy’s temple. The air between them tastes like copper and mint. McCoy stays there, breathing him in, body settling around the fact that he’s wanted this longer than he ever planned to admit.
“I am going to regret the timing,” Spock murmurs near his ear. “I have a staff meeting in fourteen minutes.”
“Tell them you’re detained by medical,” McCoy says, smiling against his neck. “Technically true.”
“Technically insufficient.” Spock’s thumb strokes the small of McCoy’s back, thoughtful, then decisive. “I will be late.”
“Damn right, you will.” McCoy leans back enough to see him again. He touches Spock’s mouth with his thumb, slow and fond, like he’s checking a wound that healed without him noticing. “You alright?”
“I am…” Spock searches, finds the word, lets it land. “Happy.”
The word hits McCoy harder than the kiss. He swallows, and the crack in his chest he’s been pretending not to feel seals another inch. “Yeah,” he says softly. “Me too.”
They stand there, close enough to make their own gravity. Spock brushes a stray lock of hair from McCoy’s forehead with clinical tenderness. McCoy traces the shell of Spock’s ear, fascinated by the small shiver it earns him. The silence isn’t empty; it holds a shape now. It holds the promise of future arguments that end better than they begin.
“Ground rules,” McCoy says eventually, because he’s still a doctor and he still knows the value of a clear plan. “We don’t do this in front of patients. We talk if something feels off. We remember we’re both idiots under pressure who get mean when scared.”
“Agreed,” Spock says. “Addendum: you will inform me when you have not slept. Your hands were trembling earlier.”
“Medical privilege,” McCoy says, even while he nods. “You’ll tell me when your equilibrium goes to hell again.”
“I will inform you when it begins to deviate,” Spock corrects. He kisses McCoy’s forehead. The gentleness socks McCoy in the gut. “I would prefer that it deviate toward you.”
“Smooth,” McCoy says, delighted and a little undone. “Who taught you to flirt?”
“You did,” Spock says simply.
McCoy laughs and pulls him in for one more kiss, sweet enough to cool the edges. “Get to your meeting, Mr. Spock,” he murmurs against his lips. “Before I write you up for insubordination.”
Spock straightens, reluctant and radiant. He touches McCoy’s cheek with two fingers in a blessing that leaves heat in its wake. “I will return at nineteen hundred hours with dinner.”
“Bring something with spice,” McCoy says. “Bring yourself mostly.”
“I will bring both,” Spock promises.
He reaches for the door, then stops and looks back. The sight pins McCoy more gently than the wall did: the most composed man on the ship, hair slightly mussed, mouth kiss-reddened, eyes bright in a way that looks like starlight found a mirror.
“Doctor,” Spock says. “Thank you.”
“For what?” McCoy’s smile won’t quit.
“For meeting me at the door,” Spock says, and leaves.
McCoy leans on the desk and touches his mouth like he’s confirming a diagnosis. His heart slows, then steadies. The office hums again, ordinary and brand new. He straightens the collar of his shirt, shakes out his hands, and opens the door to sickbay with a grin that refuses to hide.
Happy. He is happy. The word slides into him and settles in the place he saves for stubborn miracles. He orders a stimulant patch for a nurse, approves a scan for a crewman, and catches his reflection in the glass. The man looking back seems younger by a year and older by wisdom. He thinks of a meeting at nineteen hundred hours and of a dinner that tastes like heat.
The argument never resolves on paper. It doesn’t need to. The equation changed. He feels it in the way he breathes easier, in the way his shoulders drop, in the way the ship sounds almost like it’s purring. He rolls his eyes at himself, wipes the grin down to something vaguely professional, and gets back to work with a heart that finally, finally, has somewhere to go.
