[Peter is at best only kind of involved in some aspects. He minded his own spider business.]

I mean, a lot of the world saving stuff is kinda complicated anyway. Not to mention like... Mr. Stark and Steve had like this big fight in that airport and broke the Avengers up, so they were not friends for a long time? I dunno all the details obviously. I only met Mr. Stark and Steve because of the Avengers falling apart.

Oh, actually, Mr. Barnes is here. He's really nice, just kind of quiet. I don't think Mrs. Potts is here, I feel like Tony would not be having any parties if she were.
