I have heard all 5 of the books on tape for years now, I love 
Jim Dale's voice, so I put on a tape before I go to sleep and 
am lulled off to sleep, but I have a few questions that need 
to be answered:  That time turner, what makes us think that he 
has not used it to see what is going to Harry? He can't interfere 
with what is going to happpen, but he can keep Harry safe... And 
why not tell him about the eye contact thing?
