Otherwise, Wormtail's hand shouldn't come out, should it? Unless the soul of his hand is also trapped in Voldemort's wand...

If someone did Priori Incantatem on Voldemort's wand again, now that the hand, Harry's parents etc have been "freed"... would the same things come out again? Or has it "done" those ones now, and would have to start from before the ones that came out?
