Plus, she likes me. That comes across. There are a couple she can't stand (Tye) but that's personality differences, not a butch attitude.
That should have read "she likes meN" !!! was distracted by a telephone call
I think most of her supposedly butch attitude is really just self defense. One way or the other she is still a chick in a male dominated profession (how many female Viper pilots have we met, I think 1 other and Starbuck trained her) and if she doesn't act like one of the guys she won't have a social group. Lots of female soldiers or cops in the real world have a real badass attitude in uniform (if you ever really want to get beat up bad disrespect a female cop, they do not take abuse at all), it's the only way to get by in a job that's generally considered outside their gender role. People question them for their chosen work, and all their co-workers are used to hanging out with guys.
