...derations. The script was sans that stuff remember, when Marvel wanted to add that and the Avengers was when Wright walked. So to an extend it was forced to put that sequence where it was. But it worked on a different level. Personally I think the idea of Spidey being "at the start of Civil War" works, but only if he's unmasking, theyc ould play with the comic imagery so instead of it being publicly, he's revealing his identity to Stark or Cap for example (which we find out later).
