I'd love to see a definitive "Ro Laren's history" story. I've been told there are one or two versions out there about what happened on Garon II that made her such a disgrace in Starfleet at the time of her introduction on TNG, but somewhere in the DS9 post finale novels there was a scene where Vaughn told her "I know what really happened" that seemed like a tease for an eventual definitive version of that part of her history.
