katy: So you think Quirrell was wearing a lead-lined turban and Dumbledore couldn't pick it up on his radar? LOL Good one.

Buffy: I have the same problem with Dumbledore and the Time Turner. If you can use the Time Turner to save creatures before they die, then why didn't Dumbledore go back and save Lily and James Potter? Can it only be used on the same day that someone died? But wouldn't Dumbledore be the first to know who Voldemort killed? And if he suspected that Lily and James were on Voldemort's hit list, why couldn't those two have had a portkey nearby at all times that would allow them instant escape? Trouble is, we don't really know that much about how Dumbledore operates.
