Histocompatibility 8,331 words Buck/Tommy Alternate first meeting, s4e5 "Buck Begins"-divergent
On the day Buck learns he was someone else's homegrown defense system, a handsome stranger keeps him company, keeps him distracted, keeps him laughing, and then keeps him safe.
A high and sweet chuckle comes over the line. "I don't know if I can trust the word of someone who thinks the week starts on Sunday." The laugh comes busting out of Buck anyway, loud enough that he's able to ignore the written complaint his headache nails to the inside of his skull. "Riddle me this, TK: why does every calendar start with Sunday if the week starts with Monday?" "It's not my fault Saturday and Sunday look weird when they're next to each other," TK says cheerfully. "Doesn't mean it's wrong. And my name's not TK." "What does 'TK' stand for?" "Thomas Kinard. Call me Tommy—please. Thomas is my father." There's something about the way Tommy says 'father' that plucks a familiar chord inside of Buck, and the note it plays is an entire symphony that tells the tale of years of disappointment and resentment. Buck curls into himself so he can shield the speaker with his shoulders from the open air of the bedroom. "I vaguely remember you saying something about dropping some of Lake Machado on my parents' house. Is your dad's house next on the list?" "Nah, if I drop anything on his house, it'll be wet cement." Snickering, Buck lays back on the bed and cradles the phone with a hand, grinning like an idiot at the ceiling. "That's not very nice, Tommy Kinard." "Maybe I'm not a very nice person, Evan Buckley." "I don't think that's true," Buck murmurs, throat full of gravel. He wants to blame it on the hangover but he doesn't think he can. And he doesn't want to. "I think you're a very nice person. You plugged my phone in." "Your battery was running at a whopping 9%, Evan. Of course I plugged it in."
