Spock chooses the most inappropriate places to tell McCoy that he loves him.
They’re looking at weird bio luminescent plants on some planet, there’s no danger and everyone’s quiet but cheerful. Spock and McCoy move from one patch to another. Along the way, Spock grabs McCoy’s arm and quickly mutters, “I have never wanted anything in my life more than I want you.”
McCoy just kinda stares at him as he walks off then shouts, “What am I meant to do with that?”
They’re having dinner with Jim and Scotty. The plates have just been out down and everyone’s quietly beginning to eat. In the lull before conversation Spock looks up and says clearly, “Leonard, I love you.”
McCoy looks at him, wide eyed, then glances at a curious and surprised Jim and Scotty. He looks back at Spock. “I love you too,” he mutters.
Spock watches him for a moment. “No, really,” he says. “I love you.”
McCoy finds himself staring, ignoring the rest of the table now. “I know, darling,” he says. He hooks an ankle around Spock’s and the contact seems to be what Spock wanted because he goes back to his meal, the dinner conversation returning to normal shortly later.
Spock has been missing on the planet for hours, they got separated earlier and realistically they can’t be too far away from each other. They finally manage communicator contact, Jim and Bones sitting together on a tree branch to maintain the connection. Spock’s speech is slurred and he’s struggling to say what he needs to say. Jim has been asking him details about where he thinks he could be, the temperature, the view, the wind.
“Is Doctor McCoy there?” Spock asks quietly.
McCoy leans against Jim’s side, getting close to the communicator to talk to Spock. “I’m here, Spock, what is it?”
“I think…” Spock keeps taking but it’s too quiet. Jim asks him to repeat. “I think I’ve broken my leg,” Spock says.
“Don’t worry, darlin’, I’ll fix that right up,” McCoy says softly.
“I believe you,” Spock mutters, “I believe you, my precious. Petakov talukh, ashel-veh. Ashayam, nash-veh pla-kur.”
“What’s he saying?” Jim asks quietly.
McCoy has his eyes closed, refusing his emotions the freedom they wanted. “I only know a few of the words, but the ones I know are terms of affection,” McCoy whispers to Jim. “We’ll come get you soon, my love, don’t you worry,” McCoy says into the communicator. Spock hums in response, saying nothing.
