In the finale battle between Harry and Voldemort, Harry leaps off a certain height dragging Voldemort down with him. This causes them both to be disoriented when they land, which ultimately places them on equal ground.
I’m puzzled as to why this super-wizard cannot deflect Harry’s push, or at the most, gain advancement in some manner or another to separate himself away from Harry by means bounding or others. Are there no methods someone of his stature could not employ to simply be saved from the common shove and drag down, despite the surprise of it all? If there are, why could they not be employed? If not- why not?
