..."Buckbeak didn't die indeed but they thought he died when they heard
the axe which is actually the axe against the fence. That is all that
they need to go back and 'save' buckbeak. Therefore, it doesn't change
anything coz Buckbeak never did die.
It's just like a circle, it has no beginning and no end. Not like a
straight line where you start and things go on and on. Not like that.
Everything happens, has to happen. Thus, making things the way they
are and why when you time-travel you must never change anything."...

Inge:
Once again the TimeTurner discussion is hard to play with :-)

If you can't (must not) change anything during a time-travel, then why 
bother go on a trip at all (unless of course getting information or 
keeping up with 3 classes) ?

It's true that HRH *thought* Buckbeak had actually died - and so they 
did what they could to *change* that incident.
Of course they never really changed anything because things happened 
the way they were supposed to happen, and Buckbeak hadn't died in the 
first place.
Still - the three of them thought he had - and as such they tried to 
change the past and save him.

So - the next time - if ever - Harry goes on a TT-Trip - how is he 
supposed to know what has *really* happened - and how much he can try 
to change ?

Tricky devices, those TT's.....
