First of all, greetings to all of you! I've been lurking for, oh, 
three or four weeks now. I always find that helpful. I've been 
tempted to jump in a few times, but I guess that now is the time. :)

Time travel has more theories than you can shake a Snitch at, but I 
very much like the position Jo uses in the books, which can be summed 
up like this:

The time-line had already been tampered with. Hoisted on their own 
petards, and all that.

Think about it. When Ron, Hermione and Harry are getting ready to use 
the cloak, they paused to listen before they passed through the 
entrance hall. What do they hear? Two sets of hurried footsteps, and 
a door slamming.

That was Hermione and Harry on their trip with the Time-Turner. 
(someone pointed this out on a dfft group and flabbergasted me, I 
can't take credit for it)

They heard the swishing of the axe, and the howling... because they'd 
already rescued Buckbeak.

Harry survived the dementors... Because he'd already come back to 
perform the Patronus.

They can't go back and change events, because it's already been 
changed. If they had gone to warn Lupin to take the potion, the 
incident with the transformation wouldn't have taken place in the 
first place. Or the second? :)

If past events are changed, then past memories would have to change 
too, as would any repercussions of those changes. So Jo wrote those 
three hours *after* the changes had already occurred, since that was 
the only things that *could* have happened.

She's good, isn't she? :)
