Sorry, Chapel was a nonentity. Kira and Jadzia really should be the main contenders here. Jadzia should be taking this in a walk, really - what a great concept for a character - they really never invested the writing in her that she deserved. Kira was better executed and Nana Visitor is one of the best Trek
actors of all time. The character development was among the best of Trek
. Remember, "yeah Damar, what kind of people give those orders?" followed immediately by the cringe. That told the whole story, that sudden cringe of regret. She wasn't the same Kira as seven years ago.
Man. I still miss DS9
