Voldemort and his cronies (including Bellatrix) are waiting in the forest. Voldemort is surprised that Harry hasn't shown up yet.
Then, Harry arrives. Hagrid, who's there as a prisoner of the Death Eaters, yells at Harry for showing up.
Voldemort casts the Killing Curse at Harry in a blinding flash of green light.
So. . .that's it? Movie over? Evil wins?
Hmm, apparently not. We flash to Harry waking up on the floor somewhere else. Is he in a train station?
Harry gets up, drawn by the noise of something under a bench. It's a tiny, bloody, skeleton-like thing. It appears to be in a lot of distress.
Suddenly, Dumbledore is there, and he remarks on how brave Harry is. He invites him to walk around with this place, which looks a lot like King's Cross, only. . .whiter and glowy-er.
Dumbledore informs Harry the part of Voldemort living within him has now been destroyed.
But, like, is Harry legit dead? Or not? It appears that he's not...
Harry asks if he has to go "back," and Dumbledore says it seems to be up to him.
Harry remarks that the snake is still alive, and Voldemort still has the Elder Wand. . .even if he goes back, the odds of success in killing Voldemort are still not fantastic.
Dumbledore basically assures him that he will get what he needs at the right time.
Harry asks if their whole interaction is real or just happening in his mind. Dumbledore says it can be both.
Harry then asks Dumbledore outright what he should do, but Dumbledore disappears.
