Scotty is wearing a kilt.
Scotty is wearing a kilt, singing and dancing to Gaelic music, and drinking Scotch the way a fish drinks water.
Bones is not yet sure how he feels about this; he can’t decide between horror, amusement, and arousal.
“What the hell?” he asks. "I mean, a man’s got the right to do whatever he wants in the privacy of his own quarters, but, um …“
Scotty pauses the music and explains, "It’s me ship’s and my two-year anniversary.”
“Two years since …” Bones does the calculation in his head. "Since you beamed aboard into that turbine tank and nearly drowned?“
"Aye,” Scotty says, grinning. "I already went swimming in the ship’s pool in honor of that, and now I’m practicing my singing so’s I can sing my favorite Scottish love song to her engines later.“ He turns the music back on and resumes singing, swaying emotionally.
Of course he has a special ritual to celebrate his anniversary of coming to the ship, Bones thinks, trying not to feel jealous of the Enterprise (and failing.) He awkwardly stands and watches for a minute, wondering if he’s even welcome here, but then Scotty is pulling him in and making him dance to bagpipes and fiddles, and the scotch is good, and he remembers that Scottish men rarely wear underwear beneath their kilts …
The next time Scotty practices his love song, he and Bones slow-dance to it, pressed closer than pre-teens at a middle school dance. Bones doesn’t understand a single word of the song, but he can feel the sentiment – warm and affectionate, like an old comforter or a chocolate chip cookie. Scotty’s got a nice voice, after he has a few drinks; Bones should persuade him to sing the next time they have ship karaoke night, save them from Jim’s attempts at hard rock, Sulu’s weird, Asian martial arts dancing, Chekov’s Dima Bilan impression.
Or maybe he shouldn’t – maybe he should save this, treasure it, be the only man to hear Scotty sing.
"You know, it’s also the anniversary of when I first met you,” Scotty whispers as the last strains of fiddle fade away.
Bones will have this melody stuck in his head for the next week, but he doesn’t really mind.
(A/N: The song I have in mind for what Scotty sings is An Eala Bhan, The White Swan.)
