According to the "leak", Peter would've continued living his life as a popular high school student before breaking up with MJ and staying away from Ned to protect him from harm.
Another interesting part about the No Way Home leak is that there are several scenes didn't make the film.
For one, Lexi Rabe's Morgan Stark was reportedly meant to appear in No Way Home.
if the leak is correct, Rabe's scecne would've featured Tony's daughter voice her support for Spider-Man.
As interesting as the leak is, it's still from an unconfirmed source, so it's best to take it with a grain of salt.
