Heaven and Hell

Seven Deadly Sins

The Doctor was shaken. There was no denying it as they drove back to the hotel in silence. Though she wasn't sure which part of the events that had just transpired shook him most. They pulled into the hotel parking lot and parked. He sat there in silence for a moment, staring out the windshield in thought.
"Who's Rose...?" She finally spoke up looking at him. She guessed the angel's appearance had been what bothered him most. That and she wasn't ready to talk about Rassilon's offer.
He shook his head, not looking at her right away. "She.. She was my partner years ago. I'm responsible for her death. I just... I wasn't expecting to see her, even if it wasn't her." He let out a long sigh, running a hand over his face. This hunt was going to be a lot more difficult than he had originally thought. God knew there was no shortage of people Rassilon could use against him.
He shook his head of the thoughts. He'd come to terms eventually. But not today. Today he'd push down the memories and guilt again. "The Seven Deadly Sins..." He began, glancing over at her. "How do you kill a sin?"
And there it was. The question she'd hoped he had already known the answer to. But she knew, even amongst the most skilled hunters he knowledge of the sins was scarce. They knew what the sins were; lust, greed, gluttony, envy, pride, sloth and wrath. But they were aware that the original sins were beings. Demons actually. High demons with power beyond compare. "The Seven Deadly Sins are demons..." She spoke softly, avoiding his gaze. She knew the position she held with her fellow demons at the moment was very unstable. But telling a hunter like John Smith would piss them off beyond what they already were.
His eyebrows knit together in confusion. He'd never heard of such a thing. The sins were just that, sins. Acting of unsavory behavior that could ultimately lead to a human to damnation. How could the Seven Deadly Sins possibly be demons? "That doesn't make any sense..." He began, pinching the bridge of his nose. They'd already had a long day and it was barely even ten am.
She sighed, leaning back in her seat, her fingers toying with the lace on her corset. "The Seven Deadly Sins were the original sins. The worst of the worst. The demons that represent them were the original ones to commit the crimes. Each one an arch angel fallen from heaven for their respective sin."
His eyes widened at her last statement. But before he could say a word she continued.
"There were eight arch Angels that fell from heaven. So naturally there were to be eight deadly sins, the eighth being cowardice. But the eighth arch angel never fell complete from grace. He never became a demon, therefore there were only seven deadly sins. Other Angels have fallen of course but none of them arch Angels." She explained, now finding an extreme fascination with her fingers.
He sat there in silence for a moment trying to process the information. It made sense. Rassilon had never been a fan of traitors so of course he'd want them dead. "And you know who they are?"
She nodded slowly. "A few of them are already dead, killed in the war between Angels and Demons years ago. Davros is one of them. The Pride sin. Ushas, the Envy Sin. Daniel, the Wrath Sin. Greed, gluttony and sloth are all dead."
He eyed her for a moment, running the names over in his head. He knew them all. He'd fought them all at some point. He even remembered a few from his life as an angel even though those memories were still incredibly blurry. But then he counted them off in his head. One: pride. Two: envy. Three: wrath. Four, five, six: greed, gluttony, sloth. Seven. Lust. She hadn't mentioned the seventh sin. "Missy, you missed one..." He pointed out suspiciously. "Who's lust?"
She let out a long sigh, shifting nervously in her seat. "I am."
He stared at her, trying to process it. If she was a fallen arch angel... Then he... He shook his head.
Now he knew the real reason Rassilon wanted him to kill the remaining sins. Because his lover was one of them. He was taunting him, trying to make him suffer even more than he already had. He wanted him to kill Missy. He probably didn't even care much about the other sins. He just wanted to see him betray her. Again.
He drew her in, kissing her lips gently. "Bloody Rassilon will pay. I swear to you..." He assured her.
She smiled at him gently. "I'm fine, love. You're the one he's toying with. You're the one he wasn't to go full demon."
He moved away from her slightly at her words. Of course. He knew that. But he'd tried not to let that thought dwell. "I'm..."
She nodded. "You're the eighth sin love. You're the one that never fell completely. You're an arch angel."
