I'm wondering how much Peter Parker knew about the Accords. Tony didn't seem to tell him much, from what we got to see. And the end credits tease I think implies subtly enough that he will be on his own the next movie.
Basically, I'm thinking the Stark/Parker relationship post-Civil War might play out just like it did in the books into the Initiative run. As in, the were not friends.
I kind of hope so. In my opinion the public has been to friendly with Spider-Man in the last 5 movies, compared to what is the norm in the comic. People don't like him, they buy into the Bugle. Until he saves one of them, and even then not always! If the Accords are in place in the long run I see Spider-Man on the illegal side of it.
