Everything is wrong, and Donna doesn’t know why she thinks that. Things are the way they’ve always been, right? They must be, because everything doesn’t just change overnight with nobody noticing, and yet…

Then there’s the blonde girl, Rose, who keeps popping up out of nowhere. Eventually Donna goes with her. What else can she do? The stars are going out, everything’s going to hell. That’s when she learns there IS something on her back, a beetle. It’s been there all along, but somehow she just… forgot.
