I think he may have incapacitated or taken Giles before he showed up at school to drug me; Giles didn't show up to work all day so he's probably been here since last night at least. He managed to pass as a plausible magic teacher for a few minutes. He may have been loitering in the library all day if scent tracking's your thing, although there'd be lots of conflicting data. Plus whatever you know from having been vampirenapped."
