I was rewatching "Ties of Blood and Water" last night and I realized two things:
a) Major Kira's character has a lot more depth than when she was screaming at Sisko's desk in the first episode, and b) The Ghemor storyline was never fully fleshed out, which means there's a fanfic in there somewhere.
On a side note, if you've never seen the ep, I highly reccomend it. It's from DS9 season 5. It has Dukat, Weyoun, and a large helping of Kira. Sisko, Dukat, and Weyoun sit down to have a drink (of poisoned kanar), Nerys and Julian have a cute moment (the actors were married at the time), and it's really sweet and sad and all those things we love about DS9.
