Even if Peter ever does work through his responsibility for Ben's death - even if he finds peace on that front - that guilt is going to live with him forever. There's no drowning that little voice out with logic. If he'd come home sooner and not been angry about their fight. If they hadn't fought in the first place. If he'd listened to his uncle even before all of this happened...

Well, regardless of Rex's reasons, Peter appreciates Rex not forcing him to talk about it. He wasn't sure how Rex was going to react, honestly; quiet acceptance is about the best he can hope for. And if Rex just wants goodwill or doesn't want to hurt Pete, or some combination of both, that's fine too.

Anyway. It all got real heavy real fast, huh? He rubs at his neck after Rex lets go, looking up at him again. "What were you gonna dare me to do?" he asks. "You sound like you had something in mind."

Not. Necessarily offering to do it but. It's a peace offering? Not quite continuing the game.
