Spoiler: this issue I think she is the real Buffy, i.e. her consciousness, but her body has been stolen. It would suck if the story we've been reading were about a fake Buffy, wouldn't it? And she's acting like real Buffy, not like a bot. This will probably be some sort of metaphor for reclaiming control over your own body etc. especially since this season has been playing with themes like blackout, (dubcon?), pregnancy and abortion. A line from the cover of #10 also seems to suggest that: Spoiler: #10 cover "Only you could lose your own body."
