-Potters v Longbottoms-

Longbottom Manor, Chorley, Lancashire, England

31st October 1981

Frank and Alice Longbottom were sitting in the dining room at Longbottom Manor, hosting a dinner party with their friends and colleagues from the Auror Department. Present with them were James Potter and his wife Lily, Rufus Scrimgeour and his wife Agnes, Sirius Black, Alastor 'Mad-eye' Moody and Gawain Robards, head of the squad that Frank and Alice were part of. The children of James and Lily were in the bedroom of Frank and Alice's son, Neville, being babysat by Frank's mother, Augusta Longbottom. Suddenly Frank felt a shiver from nowhere.

"What's wrong dear?" Alice asked her husband, "Is there anything wrong?"

"It's the wards Alice. I've just felt them shift like an attack is going to take place shortly." Frank replied, standing up.

Suddenly a bang occurred, causing Scrimgeour and his wife to fall onto the floor. James, Lily, Sirius, Moody and Robards stood up, pulling their wands out of their robes. They were ready to fight.

The invading Death Eaters, led by their leader, Lord Voldemort, blasted through the wards, giving them access to Longbottom Manor. 'Childs play these wards are, managing to blast through them.' Lord Voldemort's second-in-command, Bellatrix Lestrange, thought, smiling at her cousin, Sirius Black, who was holding his wand menacingly at her.

Voldemort barked orders at the Death Eaters, commanding them to fight whilst he headed upstairs.

"Harry, stay there and don't make a sound, all right?" Augusta Longbottom said, making sure that her great-nephew complied. Harry nodded, signifying his understanding of her order.

Augusta went between the cot with the babies and the door. No sound was in the corridor heard until a blast opened the door, throwing parts of it through the room. Augusta lost her balance and fell, only to be greeted by a cold and evil laugh.

"Good evening Madam Longbottom," the arrival to the room said, "It's funny how you are the one to keep the children safe. An old witch against the likes of me, it's hardly a fair fight."

Augusta pulled her wand from her robes, pointing it at the man. "Get out from here!" Augusta snapped, pointing her wand at him. "Leave these children alone."

"You think you have the right to order me, Lord Voldemort, around," he snarled, pointing his wand back at her. "Looks like there's only one way to deal with irritants like you. Avada Kedava!" He flicked his wand and a green light crossed the distance between him and the older women, causing her to fall wide eyed and dead on the floor.

Voldemort laughed and approached the babies who were crying. Sounds of battle could be heard below. "Adam Potter and Neville Longbottom. Now which one do I pick?" Voldemort said to himself, "I do believe the one mentioned in the prophecy to be Adam Potter, the one with black hair, according with Wormtail. Yes…I shall kill Adam Potter!"

"Leave my brother alone!" shouted a scared voice. Harry stood, pointing Augusta's wand at Voldemort. He tried to remember what the Dark Lord cast against Augusta, but when he said it, it came out as Abracadabra! It didn't matter anyway as a green light came out of the wand. Voldemort jumped backwards, avoiding the curse. Little did Harry suspect that he had actually cast a Killing Curse against Voldemort, and had it hit its target, Voldemort would have been reduced to a wraith. Harry pointed the wand again at Voldemort, thinking of trying the same thing again, however, due to a silent disarming spell, the wand jumped from Harry's hand.

Voldemort pointed his wand at Harry, spiralling it. "Crucio" Voldemort incanted, causing Harry to cry in pain. The Dark lord held the Cruciartus Curse on Harry for several seconds. After stopping, the dark lord pinned Harry to the wall and approached him. "Who are you, boy?" he asked. Harry was in pain and scared but still he faced the dark lord who wanted to hurt his brother.

"Harry Potter." he replied, trying to hide his fear. Voldemort laughed at him then became serious.

"Well met, Harry Potter, My name is Lord Voldemort," the Dark Lord replied, a smile forming on his face, "Now, the first thing I'm going to do is kill your little brother, Adam Potter. Then I'm going to kill the Longbottom boy. After that, I'm going to kill you." Voldemort turned his back on Harry and pointed his wand at Adam.

"ADAM!" shouted Harry in tears. 'Must protect Adam. Must stop bad man'

"HA'II!" replied baby Adam, his very first words, his brother's name. Harry's body glowed golden, as of his wish of stopping Voldemort was going to come true, even if the Dark Lord did not realise it.

Augusta's body glowed the same golden colour as Harry's just as Voldemort incanted the killing curse. "Avada Kedava!" he shouted in victory, flicking his wand, aiming at Adam's forehead.

Adam's body glowed golden as the killing curse struck him, creating a lightning shaped scar, then rebounded off him. Voldemort wasn't able to dodge the rebounded curse and was hit fully in the chest. He cried in pain, fury and agony and his body was consumed by a golden light, leaving only the robes.

The cot legs snapped and the bed fell. Luckily the both Adam and Neville were safe and fine. Because of the collapse, debris hit Neville, forming a 'S' shaped cut in Neville's forehead. Both one year olds were crying, with Adam also sobbing his brother's name.

"Ha'ii." Adam shouted to his brother. Harry fell on the floor exhausted and dragged himself to his brother, in order to hug him. Eventually he reached his brother, hugging him. Whilst he was hugging Adam, Harry fell unconscious.

After the battle downstairs ended, James ran to the nursery, running over to hold Harry as Lily was checking Adam next to them. Frank and Alice came in behind them to see how their son was. Frank looked however, and saw his mother was dead. He fell onto the floor next to her body and started crying.

Harry woke up and saw James. "Daddy?" asked Harry, afraid because of what had happened.

"Dear Merlin, Harry, your fine!" shouted James, holding hugging his son. James was worn out because of the battle downstairs, where he had fought, and arrested, Bellatrix Lestrange. Lily scooped Adam up from the cot and took him over to Harry.

"My baby boys." Lily cried, hugging him too with Adam, who was crying at her arms.

"Harry, my dear boy. Can you tell us what happened here?" asked a voice behind them, the clear voice of Albus Dumbledore, Headmaster of Hogwarts School of Witchcraft and Wizardry, Chief Warlock of the Wizmanagot and Supreme Mugwump of the ICW. Harry didn't let go of Lily and sobbed in her shoulder.

"Harry, answer the headmaster, ok?" asked Lily. Harry looked at his father, then at Lily and at Adam.

'The bad man came here to kill Adam.' thought Harry, 'Daddy said to protect Adam, my little brother, at any cost.' Harry came out of his thoughts, and avoiding Dumbledore's twinkling eyes, decided to lie to the old man "I..I don't know, sir. The evil man entered and said he came for Neville. Auntie 'gusta pointed the wand at me, making me tired. I just woke up now." It was an awful lie, Harry knew, but it was necessary to protect Adam, His mommy always told him he shouldn't lie, but he had to.

"Ah, I see what has happened." said Dumbledore, sighing with regret, "Neville's magic is very strong, whereas both Harry's and Adam's are not. For this reason, and this reason alone, I believe Neville is the one of the prophecy I told you and it was Neville that vanquished the Dark Lord." Dumbledore waved his wand around, trying to detect something. "From my detection charms, it seems that there are traces of the Killing Curse in the room. Somehow, Neville seems to have survived the Killing Curse. This is truly a miracle."

James and Lily looked at Harry and saw him scowl. They look at Dumbledore, to whom Harry was looking and they saw the reason. Dumbledore had a strange glint in his eyes. 'I need to protect Adam,' was Harry's last thought before he succumbed to the effects of magical exhaustion. 'Anything for Adam'
