"We bow to each other. Harry. Come, the niceties must be observed ... Dumbledore would like you to show manners ... Bow to death, Harry ..."
-- Lord Voldemort (GF34)
After Voldemort’s rebirth in the Little Hangleton graveyard, he forces Harry into a duel. He intends to show his superiority over Harry in defeating him. However, the twin wand cores result in a very different outcome when the Priori Incantatem effect produces images of the last spells Voldermort cast. These ghost figures surround Voldemort and allow Harry to escape.
