Question re-Time Turner

No: HPFGUIDX 61263

I don't know why, but I love this stuff (and, paradoxically, I hope to 
see little or no Time Turning in the rest of the books)!

Annemehr:
And, /at the same time/, a one-hour-older Hermione walks into class B.

Annemehr:
That's the magic of the Time-Turner: Hermione /was/ in class B all 
along, because she used the TT at 10:00.  Part of the magic is that 
the result (Hermione walking into class B at 9:00) occurs /before/ the 
cause (Hermione turns the TT back once at 10:00).  This is how JKR 
handles time travel in her book, although other authors have done it 
differently.

To Hermione, it looks like that hour happens twice, but to everyone 
else there is only one 9:00-10:00, with two Hermiones in it.

For an example from the book, remember when HRH were going to use the 
invisibility cloak to visit Hagrid before Buckbeak's execution?  They 
waited outside the Entrance Hall to make sure it was empty before 
crossing through it, and heard a last pair of feet running through and 
a door slamming.  Then they walked carefully through the Hall under 
the cloak.  Now, turn to the "Hermione's Secret" chapter.  Just after 
Harry and Hermione use the TT, they find themselves in the deserted 
entrance hall and:

|"In here!" Hermione seized Harry's arm and dragged him across the 
|hall to the door of a broom closet; she opened it, pushed him inside 
|among the buckets and mops, then slammed the door behind them.

See? When HRH are under the invisibility cloak "the first time," they 
hear the time-turned Harry and Hermione run across the hall and slam 
the door, /because/ Hermione is going to time-turn the two of them 
back there when she gets to midnight.  The scene never happens without 
this.

Similarly, when the patronus saves Harry from the dementor's kiss, it 
only ever came from time-turned-Harry, for the same reason.  The Harry 
in the grasp of the dementor just doesn't know this yet.

I hope I've helped, and though I feel quite sure I'm right about this, 
I'll note that not everyone on this list agrees with me!  And thank 
you for something to do while I wait (and decide which two socks would 
mismatch best for tonight)!
