Snippet of what's to come:
The one with the power to vanquish the Dark Lord approaches... born to those who have thrice defied him, born as the seventh month dies... and the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not... and either must die at the hand of the other for neither can live while the other survives... the one with the power to vanquish the Dark Lord will be born as the seventh month dies....
Harry listened to the prophecy over and over, memorizing every syllable that was spoken.
"Either must die at the hand of the other," he murmured, "for neither can live while the other survives."
Harry sat back and repeated that line.
"Either must die at the hand of the other, for neither can live while the other survives... so..." Harry tapped the floor irritably while his brow was furrowed. "So can we only die if we kill each other? If he lives forever, will I live forever too?"
Harry considered all the times he should have died, could have slipped away to death so easily. He hadn't though. Because he was a survivor, because he was surviving.
So Timmy was living because Harry was surviving.
Because... because he was carrying around Timmy's soul inside of him.
When Harry floo'd back to Snape's quarters, he calmly sat down on his sofa and tilted his head curiously at Snape.
"How the fuck am I supposed to 'vanquish the Dark Lord' if I have to die before he can be killed?"
Snape folded his hands together on his lap and gave Harry a small smirk while his eyes glittered with what looked like mischief or danger, maybe both.
"We kill Albus Dumbledore."
