Obviously we know that Sisko being taken to be with the Prophets was up in the air after the show ended only to return at some point but there were a few other unresolved character stories by the end of the show. 1. What happened to Tom Riker? Does he have to remain in prison the rest of his life or does Kira somehow live up to her promise and get him out? 2. Kurn - Worf's brother - After the Dominion War and Worf's new position in the Klingon Empire, does advanced medical treatment give Kurn his memory back or does he remain with the family that adopted him? Is there anyone else I am missing please feel free to mention them?
