What Does Spider-Man: Far From Home's Trailer Mean For Avengers: Endgame?
5. If There Is A Time Jump, It's Then Reverted
One of the major rumours for Avengers: Endgame is that there's a considerable time jump from Infinity War, which is mostly backed-up from an older actress being cast in the role of Cassie Lang.
The Endgame trailer didn't give us a definitive answer to this either way, but since Cassie will be a teenager in the film (if the reports are true), then we can work on the assumption a time jump does happen.
If that is the case, though, it also means the time jump is reversed as well. They may go into the future - the time travel doesn't have to be limited to the past - or the story might start there, but Spider-Man: Far From Home picks up with Peter and all his friends still in high school, which means it cannot have jumped forward multiple years by that point.
