[ Matt can sense the way Peter's panic rises, the obvious guilt and turmoil rolling through this poor kid. It'd be too much to handle for an adult, never mind a teenager. He's just gonna work himself up into a panic attack if he keeps going like this. ]

[ Matt sets his other hand on Peter's shoulder, steadying him. He may not know Tony Stark or the Avengers or be up in the Big Leagues where Peter is, (or be able to control whether this is the afterlife or not? God forbid,) but he can still talk to a kid who's stressed and scared. ]

Tony Stark is a genius -- he saved the Earth before. He'll do it again. You don't have to worry about that anymore, okay?
