So, Hiro let his father die? You'd think after finding out it was Kensei he would stop the whole thing...
wouldn't work if he tried. Just like with Charlie, if he tries to go back and do things himself, it won't work. had he saved Charlie or Kaito, then he would not have had a reason to go back, thus they would have died w/o Hiro, so he would go back and save them again, ect.
If you're staring to get a headache, then you get my point. Anyway, he's eventually going to learn that the way to fix things is to make sure he has a reason to go back.
example: "Save the cheerleader, save the world."
