There's another thread on this site called 'Voldemort has Harry's blood'. There are heaps of interesting thoughts there - of course!! - but one keeps haunting me:
Does Voledmort's needing, taking and sharing Harry's blood, tie Voldemort like a wizards' 'life debt'??

This 'life debt' thingo has been kinda raised but never really explained. Has anyone any clue??

I can't find my PoA but I think it's talked about /hinted to in that in reference to Petigrew owing Harry but I might be mixing my chat theories with cannon. HELP!! ???? Who can find a reference to life debt
