"Besides, the world isn't split into good people and Death Eaters. We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are."

-Sirius Black - Order of the Phoenix (movie)

Prologue:

"She's beautiful, Sirius."

"Of course she is, Remus, she gets her good looks from me."

The werewolf rolled his eyes.

"No, I'd say it was 99% Claire, 1% you."

Sirius put his hand over his heart and a look of mock indignation overcame his features. Remus saw him turn to the room they'd left mere moments before. A Healer was attending to a woman with reddish-brown hair. The woman was holding a small bundle in her arms and smiling.

"Have you told James and Lily?" asked Remus, "You know Lily'll kill you if you don't."

Sirius sighed. Lily and James Potter had become parents a month previous, to a son they named Harry. They'd named Sirius as his godfather.

"I was going to pay them a visit this week, but Dumbledore -"

Remus nodded in understanding.

"I'm sure they understand," he said placatingly. "The organization's the only thing besides the you-know-what that ensures their safety."

Sirius nodded, knowing that Remus was referencing the Order of the Phoenix, and the Fidelius Charm. Remus had heard that James had asked Sirius to be Secret-Keeper.

The whole reason for the charm was because the Dark Lord Voldemort, the most evil wizard since Grindelwald himself, had targeted the Potters. Remus had heard something about a prophecy, and the fact that it referenced Harry; Voldemort was set on killing him.

"Sirius!"

Sirius flinched, then muttered,

"Claire." He hurried into the room. Remus watched them talk quietly for a moment, then Sirius looked up and beckoned to him.

"How're you feeling, Claire?" asked Remus as he walked into the room.

Claire smiled tiredly.

"I'm wonderful, thanks Moony." she said. "Mind her head, won't you?" she added to Sirius, who was now holding the infant.

"Have you picked out a name?" asked the werewolf.

"We couldn't agree," said Sirius. "So she picked it out."

"Annamaria Louise Black," said his wife proudly.

Sirius sighed exasperatedly.

"She couldn't do something simple."

"It's pretty." said Remus with a shrug, and snorted when Claire stuck her tongue out at Sirius. "Suits her."

Sirius was staring at Claire.

"Ask him, love," he murmured.

She looked up at Remus.

"Would you be her godfather?" she asked.

Remus's jaw dropped. There was absolutely no way - no possible way he could do such a thing...if something should happen, he could not raise the child. He would be putting her in danger.

"No rush," said Claire hastily, reading his expression. Damn her, how was she always able to tell what he was thinking? Maybe he was just too obvious with expressing his emotions on his face.

A minute or two passed, and then Remus nodded.

"Mmph."

Remus was vaguely aware that someone was shaking him.

"Dad, wake up!"

He opened his eyes and looked up to see a young girl staring at him. She had shoulder length reddish-brown hair, and grayish-blue eyes.

"Oh," he said sleepily, "Thanks, Anna. Did you finish your History of Magic essay?"

"Yeah," she replied, "d'you want to look over it?"

"Later," he yawned, "We ought to go to Diagon Alley, and get your school supplies."

"Really? Great! Can we go now?" exclaimed Anna excitedly, "I really want to visit Flourish and Blotts, see if they've got anything new, that's interesting! And Quality Quidditch Supplies as well. Oh don't worry," she added, seeing the look on Remus' face. "I know we're only going to get my school things. Can we go now?"

"Anna, it's nearly midnight. We'll go in the morning. Off to bed with you."

"Okay," she said, "Good night." She hugged him, then ran upstairs to her room, shutting the door behind her.

It was over. Lily and James were dead, murdered by Voldemort. Remus couldn't believe it - how could Sirius have betrayed the man who was like a brother to him? Claire was in hysterics upon hearing the news, and even more so at the fact that Sirius had seemingly been the cause.

Miraculously, Harry had survived the attack. No one could explain how, because this infant was the first to face the Killing Curse and live. In doing so, Voldemort had vanished...and Harry, with nothing except a lightning-bolt shaped scar on his forehead, had been moved to his Aunt and Uncle's house.

"I can't believe it." said Claire quietly, as she watched Anna, now a year old, crawling about on the floor of Remus' kitchen.

"Neither can I," admitted the werewolf, "He had us all fooled."

Claire looked up, the gleam in her eyes fierce.

"No," she said angrily, "I should have said that I don't believe it. Think about it, Moony!" she said, "Sirius and James were the best of friends - he's Harry's godfather for crying out loud! Why would he betray them?"

Remus reached over and touched her hand.

"I know it hurts, Claire -" he started, but she wrenched her hand out of his grip.

"I'm going to visit Caroline." she said stonily. He watched as she scooped Anna up in her arms, and left him sitting there, hoping her sister could talk some sense into her.

A week later, there was a knock on his door, and he opened it to find a woman with black hair, holding Anna in her arms. Remus recognised her immediately.

"Caroline," he said.

"Claire's gone." she replied. "Here. She asked me to give you this." She shoved a roll of parchment into his hand as she entered the small cottage. Remus unrolled it, and read the following:

Moony,

I'm sorry to do this, but I've gone to track down Sirius. I won't believe he betrayed James and Lily. It's too insane for me to even contemplate. I ask that you look after Anna for me until I return. I've spoken to Caroline, and she has agreed to take Anna during the full moon.

Claire

Remus looked up and stared at Caroline, mouth agape.

"I know the full moon isn't for another month." she said softly. "and if Claire isn't back by then just use the Floo."

Remus looked down at Anna as Caroline used his fireplace to travel back to her home.

"It's just you and me for now, I guess." he murmured.

Remus sighed as he recalled that night. There was now no question that he had come to love his best friends' daughter as his own. The question was, what was he supposed to tell her? She'd already tried asking questions, and he knew he couldn't put them off forever. Caroline was having the same problem.

As far as Anna knew, her mother was dead. Remus had explained it to her the summer before she started at Hogwarts. Claire had been killed by Death Eaters three weeks after Caroline had left Anna with Remus. Alastor 'Mad-Eye' Moody had recovered her body and had gone to tell Claire's sister.

The only thing Remus and Caroline did not dare tell Anna was about Sirius - who was now imprisoned in Azkaban. Guilt overcame him; he knew Sirius would've wanted his daughter to know the truth.

He did not sleep well, and when he awoke hours later, it was to Anna impatiently shaking him.

"Let's go!" she insisted, "It's nearly noon!"

"I'm up, I'm up," he said groggily, "Give me twenty minutes, then we'll go."

Anna sighed irritably and hurried back downstairs. Remus got up slowly, and went to get dressed.

Okay it's not much, but I hope you liked it, and it will get better! Please leave a review on your way out!
