I don't understand the whole Spitfire rage going on right now. IMO her new voice is the least of this episodes problems. On that note, hasn't she only spoken one time in the entire series before today? Who said her voice has to be set in stone from that one time when she had a couple of lines? And of course she's going to act like a bitch, she's been put into this Drill Sargent role, she's not supposed to be nice under this circumstance. But again, when was it decided that Spitfire isn't a bitch? As I said, she only spoke once before, and at the time she was making a special public appearance. Maybe what we saw before was her more subdued side, and this is what she normally acts like.
