When Harry opens his eyes, he sees Cedric lying dead on the ground. Oh man.
The hooded figure is pulling Harry over to a tombstone.
The tombstone reads: "TOM RIDDLE" (32.21).
Harry recognizes that the hooded figure is Wormtail.
Wormtail ties Harry to Tom Riddle's tombstone.
Harry sees a wriggling bundle lying at the foot of the grave.
He thinks it's a baby.
But, nope, it's not a baby: it's something else, something horrible.
It's "hairless and scaly-looking, a dark, raw, reddish black. Its arms and legs were thin and feeble, and its face – no child alive ever had a face like that – flat and snakelike, with gleaming red eyes" (32.34).
Wormtail lowers this vile thing into a cauldron filled with liquid.
Harry wishes, "Let it drown [...] please ... let it drown ..." (32.36).
Wormtail begins a spell.
He throws a soft powder into the cauldron: "Bone of the father, unknowingly given" (32.38).
Then, Wormtail cuts off his own arm and throws it into the cauldron (um, what?): "Flesh – of the servant – w-willingly given – you will – revive – your master" (32.41). Pettigrew has really gone off the deep-end.
The last ingredient for this spell is "B-blood of the enemy ... forcibly taken" (32.45).
And that blood is Harry Potter's.
Wormtail uses a dagger to cut the inside of Harry's arm.
The liquid inside the cauldron turns white.
"A surge of white steam billowed thickly from the cauldron" (32.50).
And then, appearing in front of Harry, is the resurrected Voldemort.
