I agree that Peter makes sense, but he shouldn't be here if he already a member of two Avenger teams. See this why Marvel has been getting under my skin, they make such a big fucking deal that Peter being married ruins his character yet the same people force him onto team after team. Peter Parker the eternal outsider is on more teams than everyone else except Wolverine. Peter Parker is racked by uncertainty, he is always afraid that he is going to make another mistake that costs someone their life which is why he puts up the bravado. He doesn't work in a permanent team setting because of this. He could work with the Fantastic Four because they weren't a team, they were a family which could provide the trust and support Peter needed so he could actually be himself. I just don't think that is what is going to happen here sadly since if they did that it would make his Avenger's appearance seem shallow.
