Spider-Man: No Way Home may have ended with Peter Parker’s friends forgetting about his existence, but a potential appearance for them in Spider-Man 4 could still make sense. No Way Home was a busy movie that focused heavily on the multiverse aspect of the story, but Peter’s friendship with Ned and his relationship with MJ was at the heart of it all. The two were a huge help in the Spider-Mans’ fight against their various villains, which is what made their conclusion all the more heartbreaking.
