Agreed, Peter should face some consequences for that little stowaway stunt he pulled in IW, but, uh, maybe Tony snaps at him a little too harshly because, you know, it scared the shit out of him. Maybe he says something he instantly regrets and wants to take back as soon as he says it. Maybe… Strange overhears him. Maybe, Strange decides that whats good for the goose is good for the gander >:3
