Harry watches underneath the floor as Dumbledore tries to convince Draco that he has the choice not to kill him. Snape then shoves Draco out of the way and casts the killing curse at Dumbledore who falls dead to the ground. Snape grabs Draco and flees along with the rest of the Death Eaters. Later the whole school, minus Snape and Draco, gather round Dumbledore's crumpled, lifeless, body, holding up their lit wands to create light to clear the sky of the dark mark hovering above them in the clouds.
