Re: Why didn't they just keep their characters?
Sisko must have been shocked when he noticed his dad looked like a certain traitorous Admiral from TUC.
Not cannon, but how do we know that Sisko's not related to Cartwright? Nothing's ever mentioned about Sisko's grandparents that I can remember. Maybe one of them was Admiral Cartwright's son or daughter.
