In case you missed it during Sunday's highly-rated MTV Movie Awards, here's a pivotal scene from the flick.  Trying to give our hero Harry some background on the origins of their arch nemesis Voldemort, Harry's mentor Dumbledore provides memories of his first meeting with a seemingly still "innocent' incarnation of the franchise's resident anti-christ.
