I can see something extremely important happening in the room with the podium and the piece of cloth. Maybe even Harry going through it... and coming back out. It would definitely show him as being the greatest magician of all time and, say that Hermione WAS dispatched, it would be the perfect way for him to get all angry, dive in, save Hermione, come back out, golden aura, the lot, and do away with Voldemort.

You know, something like the way Hercules saved Meg in the Disney cartoon.
