We were wondering, ‘Are we going as deep as we need to at the end of the movie?’
So before it became a tag, it was really just the end of the movie: Right as he feels he’s stepping up as Spider-Man, he has the rug pulled out from under him again.
We played with the idea that Peter is the one who sacrifices his identity out of necessity during the final battle, then it seemed more interesting if Mysterio tricks him into doing it, but any time we wrote a version where he was being revealed to the world in that battle, it felt like it diminished the victory.
