there have been lots of talk about the return of emma stone to play the role gwen stacy in the amazing spider man 3. lots of people suggested that she will return as a clone after the jackal was upset about her death. however, i have a new suggestion.
after the death of gwen, peter becomes depressed. spiderman will disapper and there will be lots of crimes. a person from oscorp knows that peter is spiderman that is after seeing him on camera footage. he offers help to peter and then both of them build a time machine. peter goes back in time and is able to save gwen, but he has only 1 chance to save her and get back to the present
thats my idea guys if you have better ideas leave it in the comment. PEACE✌️
