Oct. 31, 1981.
Voldemort was at Godric's Hollow. "Ah, there it is, the House of Potter at last," he said, as he approached the door. As he was about to open it, Wormtail (a.k.a. Peter "you-betrayed-James-Lily-and-Harry-to-Voldy" Pettigrew) Apparated right between Voldemort and the door.
"My lord," he said, looking furious, "even though I have told you the location of the Potters, I shall not let anyone, least of all you, kill one of the Marauders."
"Stand aside, Wormtail. Or you know the curse."
"Oh, really?" Wormtail opened the door. "OI! JAMES! I BETRAYED YOU TO THE DARK LORD, FLEE THIS PLACE AT ONCE!" James appeared, holding his wand. "Really, Wormy, this is not the time to jo- VOLDEMORT! You're dead, Mister," he finished surprisingly calmly.
"Oh, I'm so scared! Wee-Potter is going to kill me! You little blood traitor! CRUCIO!" But Wormtail stepped between them just in time. Voldemort took off the curse and said, "Go back, Wormtail. You needn't die. I just need to kill Potter's son."
"Oh no. You kill me first, you TOM MARVOLO RIDDLE! PURE-BLOOD PRAISER WHO HIMSELF IS A HALF-"
"Avada Kedavra."
Green light shot from Voldemort's wand and hit Wormtail full in the... hand. He dropped dead at once.
Lily appeared from a door, saying "James, stop making fictional characte-", when she saw Wormtail, Voldemort, and James, realized what had happened, and said "V-Vv-VOLDEMORT!?"
"YOU IDIOT! YOU KILLED WORMTAIL!? Expelliarmus!"
The 13 1/2 inch pheonix and yew wand zoomed out of Voldemort's hand, and into James's, who threw it away at once.
"Potter, oh, Potter, you don't know my powers, do you? I can perform any curse wandlessly. You're dead. Avada Kedavra!" Another flash of green light, headed at James's head. Lily covered her face in her hands. Then several things happened at once: the green light bounced off James, and hit Voldemort in the... eye. The front of the house blasted away into non-bieng, and Voldemort's body was covered in green fire. James nearly fainted, and fell down. Lily opened her eyes, and saw, to her surprise and astonishment, James stirring. He stood up, rubbing his foreheard. "Ow! Lil, it's hurting! Look!" He released it, and Lily gasped.
There was a scar, shaped like a lightning bolt, on his forehead. He had survived the curse, with nothing but a thin scar."Oh, James, I w-was s-so scared!" She hugged him. After he was released, he said, "But how? How did I survive? Not that I'm complaining, but... strange. I'll send an owl to Dumbledore."
"No need, James. I'm here." Dumbledore had Apparated into the room. "What has happened? Your house is covered in green fire, so I would assume Voldemort was here."
James narrated the whole incident. Dumbledore said, "James, Mr. Pettigrew here saved you from Voldemort. When he took the Killing Curse, he gave you the highest possible level of protection. Sacrifical protection. It is the only known way of surviving the Killing Curse, and was untested, until today. You, James, are the Man Who Lived."
