He shrugs in response to the question, mouth twitching up in a tiny, bitter smile. It's hard to just say "I'm okay" nowadays--there are good and bad days. Days like after Derek died, after Scott just cracked, when he knew he was going to go back and threw himself at the Jabberwocky just to get a couple of days where he didn't have to exist. It didn't make him feel any better; it brought him back screaming and seeing visions. Not his brightest decision, certainly, but Stiles just--he stopped caring. He stopped being cautious. If he died, who cared anymore? He was just going to come back, and maybe it would be some goddamn relief. "This is supposed to be some kind of opportunity, right?"

That's about all the optimism he can manage, and very indicative of his mood.

Stiles looks Isaac over for a second. He's kind of--he just gets it. He knows. He watched what happened to Scott and tried everything he could to stop it, because when their beacon of hope disappears it leaves them all stumbling. Allison and Derek dying--finding their remains, together, had been one of the most heartbreaking sights of Stiles' life, and he remembers throwing up afterwards, remembers the panic, remembers just shutting down.

So he picks up his hand and taps Isaac's on his shoulder once, like it's solidarity. "'m glad you're here too, dude."
