> YAY. You are posting :). Okay, so if they were already there and I know we can't, but that means that you think that the events in the book in this episode happened the same way as in the "Medium that cannot be named"? At some point in time I actually thought that I got the time travel in PoA pretty well and that JKR explained it so well, but after not rereading the book for so much I think I am getting confused again. I think I may go dig up some old posts on this topic.

     OK, here's time travel 101: When you time travel into the past, you 
cannot change anything in your own past, particularly the fact that you 
had traveled back in time. However, you can do something that appears to 
have changed the past as long as everything happens the way you 
remembered it.

     JKR, of course, broke the rule by having Harry save his own life, 
because there is no explanation of what happened at the beginning of the 
time loop; how Harry survived to go back to the past to save himself. 
But it's her story.
