I'd be down for either option though if we play out Voldemort coming back without Harry Potter, things might not make as much sense xD

That being said, we can also make it even more AU and say that one of his minions (I vote personally for Lucius) is trying to bring him back with thay potion thing and he scored up, not actually grabbing Potter but one of [i]our[/i] characters at the end, and we have go stop him yadda yadda. This could take place during the third task, in the graveyard like in the canon.

Or we could do something totally different! Haha I'm just tossing out ideas.
