Maybe he can save the kids or something, if he has in truth reformed. Then the two of them can have a private scene where they can talk. Just an idea I had. Up to the player, but I think it would be great if he had reformed by that scene at the end of the movie, 7 I think it was.
As for the reunion in your story, that could be after the 5 years is over so there can be 2 reunions, this one during his exile, and the true on that can take place after his exile is over.
