Re: Gwen/Flash
Mary Jane is still the same Mary Jane, and Harry is still the same Harry. Pete is new. This is the fifth one, and I don't know enough about him yet to tell. Harry injected a portion of the goblin serum, so be cautious in interactions with him.
Personally, I trust Mr. Rogers and Ms. Carter. Doctor Banner isn't ours, but his intentions are good. Mr. Stark has been really ill, and I don't think he's mobile, based on the fact that I never saw him around Stark Tower during my time there for the past few weeks. Professor Xavier has been helping the pulse mutants, so I think he's trustworthy, though I don't have any personal experience with him. The previous Peter worked with an Avenger named Jess, and she went to find him when he was in trouble, so I think she's a safe bet too.
