Probably growing up as a hater? The timeline all changed when old bruce willis came back making the new time all plausable. What old bruce willis didnt know, was why the rainman was doing what he was doing. It was because of him. joseph gordon levitt Changed all of this by commiting suicide.

This is what makes no sense. I think it's a giant plot hole and ruins the movie for me.

Spoiler!

The events that happened after Joseph Gordon Levitt didn't kill Bruce Willis never happened in young Bruce's timeline because young Bruce killed his older self right away. Then he went to China and met the chick, etc.

They implied that that the kid became the rainmaker when he saw his mom die but the ending of the movie never happened in the 1st timeline, when Bruce was young. The kid still become the rainmaker.
