JoJo's Bizarre Adventure: Starting by Defying Fate

It feels good, I hope it will be a perfect ending, and after the end of the third main line, we can add a scene where Joe, the second child, has long discovered that the protagonist is a time traveler, and then I am curious how to deal with the iteration of the main line, whether to directly time travel or according to the timeline. The protagonist will not be in his 40s and beat the priest, right?
