Lol, my knee -jerk reaction to a question like that is to be glib and say that she's pissy about how season 6 ended. In reality, though, there's a fic I'm working on that has her being a grumpy-pants pretty much throughout. This and another facial expression that I'll probably work on later today keep popping up in my head, so I have to draw them to get them out. Plus, changelings are heck-a fun to draw.
