I've got a good Xander going. I think I get him. He moves around in my head and talks, and sometimes pushes a scene in a direction I hadn't expected. And Giles is an interestingly physical presence in my mind. I can look up from my laptop and see Giles standing in my living room, fidgeting. Buffy, well. I can't really get into her head, but I've decided not to for this go around. I'm okay with seeing Buffy from the outside for now.
It's Willow who's giving me fits. I love watching Willow in action, but she has no presence in my head. Gah!
