the very first thought nick has is that sunglasses is a prick. the second thought going through his head, though far less important, is that he probably ALSO looks like a prick, but he's not wearing sunglasses in the midst of a devastating apocalypse.
his nose wrinkles at the sight of the two men before him. apparently, his mind is already made up that nick does not like either of these people standing before him, but he's not about to turn down aid when it's literally knocking on his makeshift door.
still, he's pushing it open, stepping aside (and yanking ellis back) to give room for the two to enter. posh doesn't strike him as any better than sunglasses, but with them, nick is willing to bite.
"charming," nick drawls out, dragging a hand down his face. he barely reacts when ellis slams the door shut behind the door, settling back against the wall. "i hope you're not planning on getting too―"
"nick, find your chill," ellis chides. "we're in good company, ain't we?" he turns to give the two a bright smile. unlike nick, ellis thinks ruairi looks awesome. "wish i had sunglasses like that. my buddy keith once bought me a pair of cheap ones from a gas station. you know, the big plastic ones that are brightly colored? i wore 'em for a day once, but i lost 'em after a trip to the local bar. maaaan, i haven't bothered looking for any since."
he pauses to suck in a deep breath. "what i meant to say is, i'm ellis, this here is nick. don't mind nick, he's a surly bastard on a good day. we're real grateful for any sign of people."
"tell them everything about us, why don't you?" nick snaps. he's not sure why he's so annoyed. ellis, realistically, BARELY said anything about them or who they were looking for. maybe nick's just tired. or maybe he resents being called a surly bastard.
"whatever," nick grumbles. "posh, you can do all the talking here. what's your deal? you immune, like we are?"
"nick! you can't call 'em posh like that, that's rude man."
