One of the questions asked was how she got into the character for each scene and she admitted that she always finds it extremely difficult to switch from herself to the character, hence she prefers to stay in character all day. That means while she waits for the next take, she's "Major Kira, waiting".
That's hilarious. Well, it really shows in her performance. Most complete/fully-realized character in Trek imo. Outside of Nimoy's Spock, I guess, maybe. And in his case certain things are so iconic it's hard to evaluate.
