every read harry potter?
in the third one harry's dad comes comes out of the woods to conjure up some spell to scare dementors (or whatever) away...then later harry realizes it wasn't his dad, it was a future him.
howd the future harry as seen by the past harry know what to do? how did the future harry manage when he was the present harry? cuz if future harry is supposed to protect present harry, who protected the future harry when future harry WAS the present harry?
