Castiel POV

Many days passed and still Audia did not return. They were all kind of expecting her to, but after the third week, they sort of stopped waiting. They had figured she might come back eventually. Castiel didn't know how to feel about Audia, though his respect for her greatly increased for her (though he hated to admit it) when she gave the answer on who she'd back in a battle between angels and demons, or any battle for that matter. She didn't say that out loud, but Cas knew it was true in his hear- Do angels have hearts? Oh well, never mind that.

They had moved around a lot for hunts. Cas had to come with them because he could not very well fend for himself, and he didn't want to return to the battlefield that was heaven. He had gone back to the memory over and over again of Sam and Audia yelling at the thing that wasn't there. But the thing was, the more Cas tried to remember, the fuzzier it became. It was like a dream and all the details slipped away from him like water running through his hand.

After a month and a half, something happened. She came back.

Audia POV

She had been in The Pit talking to Lucifer. She was talking to him, and she had something to think about.

_-Flashback-_

"I don't wanna go away!" said Lucifer in a pouty baby voice, sticking out his lower lip in mock sadness. "GO!" screamed Audia, who was still in her 'full' form.

"NO!" shouted Lucifer defiantly, "I'm your big brother! I'm not letting you tell me what to do! Unless..." he had dropped the baby act and had the awful, dreadful, evil smirk back in place. "What?" cried Audia desperately, "I'll do just about anything now!" her voice turned acidic, "I remember the days I loved you, idolized you, made you my role model! You used to be amazing, now I'll do whatever it takes to get away from you!"

Lucifer looked slightly ashamed, but there was no mock, or venom to his gaze. He said this truthfully and sincerely, and she felt a tiny sliver of pity for the vile creature in front of her. This was no longer her brother. He said two tiny words that changed him and her for quite some time, "I'm sorry." he whispered faintly.

"I'm sorry you had to come to this.." she said, "What was the little 'Unless' you were talking about earlier?" He looked up, recovering slightly, but did not take up a tone of mock, or hatred, or denial. He said, "I could make a deal with you. I don't want to have to do this to you, but me entering both your minds is like a contract. You can break it by selling your soul. I may be able to give it back after as well." She just stared. She saw that her brother wasn't even lying. He meant every word he just said. Call it sisterly love, but she accepted. She was doing this for Sam as well as herself.

"This will hurt..." he said. She cringed, she knew the feeling of having your soul ripped out, and the exemplary pain of having it forced back in. He walked slowly and cautiously towards her. He handed her a leather belt, sighed, and said, "You know what to do."She nodded. She snapped her fingers and a wooden chair appeared. She sat and put the belt in between her teeth, ready to bite if the pain got too bad. Though she could handle it better than most mortals, she still felt pain. He rolled up his sleeve and reached for her stomach. He made contact and went into the spiritual temple of your body. The second his hand pierced her skin she screamed in unbelievable agony.

Then she ceased, only breathing heavy now. His hand grabbed the soul and pulled it out with a heave. When it was in his hands it looked like nothing more than blue-white, black, and gold wisps of smoke. "I truly am sorry for this." he said in a lamenting tone.

"It's nothing." said Audia in a tone less voice, with a blank look set on her face. A black tear oozed down Luci's cheek. This was, after all, his little sister he was hurting. He grew up with her. She was a feisty little angel who always seemed to be up to something. She got her way an awful lot too. Really only Lucifer, Gabe, Anna, Hanna, and Balthazar had ever met her. She was really something different.

He wiped the tear away promptly and sat down. "I can't give this back for three months... It may be too damaged, and dangerous to try to give it back once it's been down here" he gestured around The Pit, "for three months.."

"We have to give it a shot.." said Audia. She smiled a smile that was slightly emotionless, "If we get out of this, I swear to Dad I'll visit you once a month." He smiled at her. "Wanna sing our song?" she asked with some genuine enthusiasm. He nodded vigorously with a smile. They began to sing, "I am the innocent. I am what could've been. The dreams you talk about. Now left on broken skin..."

They sang that a good twenty times, all the while Luci was dancing like an idiot. On the seventh time Audia joined in. They acted like the world was as it was, and heaven was peaceful. Nobody was tearing at another's throat. Heaven was never truly peaceful, but they used to be happy... Happier. Before she left Lucifer told her this, "Tell Cas I'm sorry." I digress. Back to the story.

_-Flashback Ended-_

She appeared on a hard wooden floor in a motel room not so different from the last one. It was very early. There was, however, a difference this time: This time she appeared in front of Castiel. He looked at her with surprise, then he hugged her. She hugged him back, trying not to imply that she was guilty. He, however, looked past all this. He pulled away looking alarmed. "What did you do?!" he asked in a panicked whisper.

She sighed and spoke very fast, as if going quicker would limit the outraged outbursts and protests that were sure to come from Castiel's mouth, "Well I was in The Pit talking to Luci where he said to get out of me and Sam's heads he would make a deal with me so I sold my soul and he said he give it back, but it takes three months to give it back and my soul might be broken, destroyed, or very badly damaged where as to it wouldn't be able to go back inside me." she flinched and gritted her teeth, awaiting the outburst.

He just stared at her for a second in shock, then he opened his mouth, "YOU DID WHAT?!" She cringed. Sam and Dean popped up and in one swift motioned had pulled the knives out from under their pillows and stood up. They saw Audia, dropped the knives, smiled, and walked over to hug her. Dean, however, got there first. He hugged her and whispered to her, "Don't ever do that to us again." She smiled into his shoulder and nodded. He pulled back, and close on his heels was Sam who hugged her next.

He had to stoop down to hug her, seeing as she was rather short, and he was huge. "Nice to see you too Gigantor.." she mumbled into his chest.

"He Hybrid.." he chuckled into her hair, and then pulled away. "Why'd you yell Cas?" he turned to face the Angel in the corner who looked to be in a foul mood and his face showed it. Dean jumped. "Why're you angry?" Sam also turned to Cas. Audia followed suit, but profusely avoided eye contact. He told them everything she told him, word for word.

They both were fuming by the end of the story. "What?! She sold her soul?!" Sam yelled.

"Lucifer! That son of a bitch! I'll kill him!" yelled Dean.

"Shut up!" shouted Audia, "Look, it was my own choice. I'll face it when the time comes."

She hadn't expected them to care so much... I mean, of course she expected them to care, but she never expected them to act like her brothers. But that's exactly what they were to her: Brothers.

Three months came and went while Audia stayed with the Winchesters and Cas, going on hunts and surviving. It turned out that she was nearly a better hunter than Dean. They outshone each other at different times.

Audia stood at the door of the abandoned house her, Sam, Dean, and Cas were staying in taking in the cold, brisk morning. The grass was dusted with white powder and the windows were laced over with frost. She stretched out her wings and they were met with a chilling sensation that sent shivers up her spine. She was about to be in a place that burned hotter than the sun.

She glanced back into the kitchen to look at the table. She saw the note she left that said what Lucifer had asked her to tell Cas folded up neatly beside a breakfast she had made. She turned back to the outdoors, took a deep breath, and with a whoosh and some wind, she was gone. She prayed last night to Dad to ask him that her soul be in tact. She hoped she listened

She appeared in The Pit to see Lucifer sitting on the floor holding her soul. She was relieved to see it was still in tact... Wait, a piece was missing! She opened her mouth in a panicked way, but Lucifer put up his hand quickly and opened his mouth to explain, "It's only a little piece! Once I put it back inside you, it will heal over in six months." he cringed.

"Now we have to put it back in." she said with a sigh, relieved that her soul would heal. She snapped her fingers and a wooden chair with a leather belt appeared. She sat on the chair, and put the belt in her mouth. Luci approached her, holding the soul tenderly. He gently put his hand close to her stomach, then again went into her inner spiritual temple. It was agony for a moment, and she screamed, then she started breathing heavy.

He took his hand out and smiled at her as she took the belt out of her mouth. "Let us sing our glorious song." exclaimed Audia sarcastically. They began to sing, "I am the innocent. I am what could've been..." They only sang it twelve times this time. Then Audia whispered, "Thank you... Brother.." and with a faint whoosh and a little wind, she was gone.

She appeared on the walk up to the abandoned house and was met by three people. You can guess who they are. "I'm fine!" she exclaimed. A cheer went up around the group. Castiel hugged Audia tight and whispered, "I forgive him."

A month passed.

She was in the kitchen finishing up her hamburger at top speed. "Where are you going?" Dean asked as she stood up to leave. She turned around to face him. "I'm visiting my brother. And I'm proud of it." She smiled and with a faint whoosh and a little wind, she was, yet again, gone.

Done with the story! Yay! Hope you people enjoyed it... If you even read this far... Comment if you know the song that Audia and Lucifer were singing, and who it's by... (Knowing that song does not make me a Satan Worshipper. -_-) We all love Supernatural here.
