She has a very masculine, "tough guy", persona. She dresses like a complete tomboy and is often in male clothing. She rides a motorcycle. Even if she wasn't gay, she is some kind of queer.
And now let's talk about her relationship with Blair. This relationship can best be described as a love/hate relationship with a chemistry that is so thick that it can be cut with knife. The tension, interaction, and attraction cannot be denied. So many slash fics have been written about the two of them is amazing. Even though they do add love interests and etc, I'm not completely won over by those distractions.
In one of the beginning episodes of the first season, the Facts of Life discussed lesbianism, and how one of the students was picked on. Unfortunately, I have never seen the episode, but the fact that it was talked about does show that it's not a subject they were unwilling to approach.
What do you think? And who else do you think is an "in the closet" character that probably will never come out. Darlene from Rosanne comes to mind, who by the way is played by a gay actress (this I did not know until about 2 months ago!)
