If Fate exists, then anything that happens has already been determined, even time travel.
How can Crono not be the hero of time when they had that whole entity talk during that Robo side quest. They even said that someone wanted them to see it all. Because you're always going on about that scene in other posts, like how the entity does exist bla bla bla.

And I never said Serge's death wasn't cannon. I said it was pre determined, so that in 1020 Kid would have to go back in time to save him, which was pre determined too.
