Tough to guess whether it's going to be something stupid and played as a joke or something serious. Probably something somewhat serious that'll still be played as a laugh. Maybe. Or like, he's a ghost now but doesn't mind or something ^^;
Anyway, who the fuck would you just walk up to somebody and ask them about their trauma? I mean, imagine someone going "hey, long time no see! You still traumatized from when you were getting raped? I see, I see."
