[Cami is completely right about all of it. It's a weird mix of emotions. There's misplaced anger at Greg for wandering away, but mostly anger at himself for not noticing, for not doing a better job at the whole older brother thing. He's sad, of course. There's this sense of mourning, as he mentally prepares for the worst - the possibility that he might be stuck forever and that he might never see Greg again. But the weirdest is the nothing, the numbness that comes from knowing this is something that can't be changed. No matter what he does, no matter how he feels, he can't change the fact that Greg isn't here and that Greg might not ever come back. He might never go home. That nothingness protects him from everything else, but he feels most guilty about that. You're not supposed to feel nothing when your brother vanishes, but he can't seem to summon up the energy for anything else.

Nothing feels right or like what he's supposed to be doing, so to hear Cami say so, to have her tell him it's okay and normal...it helps. It really does. It's okay.]

I should have been paying closer attention. Like, maybe if we'd been together we would've left at the same time? I-I don't know if it works like that, but...

[Then he looks up and really notices Cami for the first time, with her eyes full of tears. It finally clicks that maybe she isn't familiar just because of her profession, and that maybe this isn't just about him. So, he turns it back on her.]

...um. Are-- are you okay? You don't really seem like it.
