It was a dark, clear evening with the moon just about to rise. Young Remus, perhaps six years old, was playing outside on the miniature playground his parents had bought for him. His mother, a muggle, was in the kitchen making cookies, and his father, a wizard, was with him outside. However, his father had a chore to do and had to leave for perhaps thirty minutes. That was the dooming of young Remus Lupin.
Remus heard a noise coming from the bushes, a sort of russling sound that animals made, so he assumed it was just a large animal, perhaps a raccoon or stray dog. But then, the creature in the bushes cackled with a cruel, harsh tone to his voice. The chortle sent chills down Remus's spine, and so he got off of his swing and began to walk towards the door of the house. A deep voice then commanded Remus to hault, and so he did for fear of what could happen if he didn't. The voice commanded him to turn around, and slowly, Remus did so. Then he a saw a blur leap from the bushes. When the blur leaped, it was man with wolf-like features, but when it reached and tackled him, it was wolf with human-life features. Though he wasn't sure if it had something to do with it, the moon rose during mid-leap. The next thing he knew, he was in a hospital, and bleeding extensively. Humanity was over for Remus John Lupin.
When he went off to Hogwarts some five years later, Remus was terrified of someone discovering his secret. Despite fear of hurting them, Remus befriended children called Peter, Sirius, and James. All four of the new friends were sorted to Gryffindor, where the brave at heart dwell. Remus expected to be Ravenclaw, the house of the brainy, but didn't object to being called brave even though the only brave thing he had done was live through this curse he'd been presented with. He told the sorting hat so, and the hat, which could speak, stated that admitting flaws like Remus did was bravery in itself.
Remus hid his secret, even from his friends, perfectly, until one day during third year. He was running late, being careless, and the moon was nearly up. When James stopped him to ask where he was going, he ran out of tmie and transformed on the spot. Sirius, James, and Peter were in for a real surprise, or so they should have been. The three, however, had been suspecting lycanthropy for many months, and they'd taken the liberty of learning to be come animagi, and the rest, as they say, is history.
For the longest time, the four were inseparable. But, as time past and clocks turned, James began to split away, for he finally had the girl of his dreams. Peter began to dread life, afraid of all things. Sirius had too much time on his hands and began to make Severus Snape's life more hellish than it already was. Peter stood in the shadows, afraid to move into the light, yet more afraid of the dark. He, Remus, had his own problems. With his friends drifting, it became difficult to once again deal with his curse, his "furry little problem" as James called it, alone.
The lonelyness that overswept him soon turned to hurt. It seemed Lord Voldemort knew every move they were planning. A traitor was suspectedly in their mists. Sirius began to suspect him to be the traitor, a thought which had never even crossed Remus's mind once. Lily would never hear of the thought, however. Remus admired her so much. Ever since Lily discovered his secret in sixth year, she'd been on his side for all accusations. Lily would lie in court for Remus, and her loyalty was affectionately returned. Lily was like the sister Remus always wanted but never got to have. His mother had been pregnant with a little girl once, when Remus was one year old, but the pregnancy ended in miscarriage. Her name would have been Emma. That's why he loved Lily so much.
Quite often, however, Remus found himself alone. He had lost Emma before he even got the chance to meet her, or she got the chance to see the world just once. He lost his parents a few months before James and Lily's wedding due to a Death Eater attack. His muggle mother had been attacked, so without hesitation, his father jumped to save her. She was struck with a Killing Curse that sent her body flying back into his arms. The attacking Death Eater used the Cruciatus Curse on him with no response. He demanded death, saying that the pain his body suffered was pleasant compared to the grief. And then he was killed, too. And now Remus was losing the only people he had left; his very best friends.
The pain he felt began to become unbearable. At first, he crawled into a bottle of alchohol and vowed to never come out, but he quickly regained his famous Remus sense of honor and righteousness. He quit drinking and turned to another pleasing substance that was much better for him: chocolate. He began to keep chocolate on his person at all times, just waiting for a situation that so required its use.
The events that ruined him came all in a row, on the same night, for on that night, he lost every single one of his friends for what seemed like perminantly. James and Lily were killed so unexpectedly. Peter was dead, killed by Sirius. Sirius was a murderer of not only one of his best friends but many muggles and sent to Azkaban. Remus was alone. So alone, in fact, it hurt to even breathe or think about continuing on in life. He wasn't even allowed to visit James and Lily's child Harry, who was sent to live with Lily's muggle sister. He was reckless, even suicidal, when he went to Dumbledore, demanding an answer for what to do. Dumbledore smiled and gave him one piece of advice. "Just keep looking forward."
Remus took the advice to heart. He managed to survive twelve whole years, after which he got a job as a teacher at Hogwarts, a school he so loved. Sirius escaped Azkaban and proved his innocence to his friend. As it turned out, Peter was the traitor, not Sirius. Both of the two felt terrible guilt in the pit of their stomaches for ever doubting the other. And then, two years after that, Sirius was stripped from him again, murdered by his own cousin. And then he fell in love with Sirius's cousin, Nymphadora Tonks. He didn't want to love her, to put her at such risk that becoming envolved with a werewolf entitled, but, after a year of her protest and demand, he gave in. They were married shortly after. Soon after, Tonks became pregnant with his child. Remus, scared, left his wife and unborn child until Harry, now seventeen and a force on his own, convinced him to go home. He and Tonks went the entire length of her pregnany, and their son, Teddy, was born. And then the world crashed down at the Battle of Hogwarts. He went to fight, leaving Tonks home with Teddy. However, Tonks followed, her love for him too great to let him risk his life alone. Remus turned his head to look at her one last time while he was dueling Dolohov, a Death Eater. He nodded to her to tell her that he was all right and for her to go on. She did so after mouthing, "I love you" one last time. He returned the loving statement, then, once she was out of sight, took the final spell that ended his life. She followed mere minutes after, and once again, they were together. Not only them, but James, Lily, Sirius, and even Peter, who had died protecting Harry, were reunited. He was home.
