It isn't in the books because I really, honestly don't believe she "always thought of DD as gay." I don't think she thought of DD as anything, it just came off a a convenient way to get an ovation out of some of the battier corners of fandom. Her original audience, the kids who have followed the books since they started, don't give a crap. Really. In fact, just to prove that point, when my son, who has followed the books one by one since he was about 7, gets home, I'm going to tell him what Jo just said.

I'll report back, but I know his reaction will be, "So? That's gay."

"gay" here being the teenage version of the term meaning, "why the fuck should I care?"
