"So, we know that Chuck didn't do it, and Amara didn't either. Are you strong enough?" Sam was talking to Lucifer, who seemed surprised that he had been asked that question.

"Me? No, not even close." Lucifer looked at Gabriel with a guilty expression and continued, "If I could, I would have tried."

It looked like Gabe was about to say something, but was interrupted by Dean. "Well then who the hell did it?"

Chuck, who had been standing silently behind them, walked over to Gabriel and stood in front of him.

"Let me see," he said, putting his hands to the sides of Gabe's face, which seemed to make him uncomfortable, "Huh, that doesn't make sense."

He stepped back and stared at Gabriel. "What? What doesn't make sense?"

"I don't see anything. I have no idea who brought you back." Chuck stood, his arms crossed, for a few minutes, silent and clearly thinking. All of a sudden, he tensed as the color ran out of his face.

"Eris."

"Who?" Dean and Sam had no idea what was going on, but the other three had grown silent and we're just staring at each other. "Who is Eris?"

"Uh... " Chuck was at a loss for words, and it was very confusing to the pair of hunters.

"Eris," Gabe said suddenly, "Eris is my sister."

"Our sister," Lucifer corrected.

"Your sister? What do you mean she's your sister? There's another archangel?"

Chuck spoke up at that time, but didn't make eye contact with anyone. "Not an archangel. My daughter."

"What do mean not an archangel?"

"Eris is my biological daughter. She was born, like you, only a long time ago."

"Your daughter?" Sam said, at the same time as Dean said "How?"

"It's a long story..." Chuck glanced away before clearing his throat. "Eris' mother is Clotho, or Nona, the Moirai from Greek 'myth' who spun the thread of life weaving the cloth of life. She controlled the lives of others and was the youngest of the fates. You've met her sister, Atropos. Anyways, I may have fallen in love..." He paused for a second before shaking his head.

"Eris is very powerful. She's the product of two extremely powerful beings. She's stronger than I am currently. She disappeared a while ago however. A little after you left, Gabriel." Gabriel sighed a bit. "I haven't been able to track her down," Chuck continued,"she knows how to hide herself." He sighed softly.

"So, this Eris chick is a goddess? And what, your half sister?" Dean's scoffed. Gabriel nodded a bit. Chuck took his seat. It was still tense between the three heavenly beings. Lucifer childishly stuck a forked tongue out at Chuck when he had his back turned. "Why would she bring Gabriel back?"

"My sparkling personality obviously"

"She was always partial to Gabriel and Lucifer. Raphael and Michael... not so much." Chuck explained, rubbing his temples. "Which is understandable. Those two are major dickwads." Dean supplied, only to be silenced by a stern look from his brother.

"We can't have someone powerful enough to bring back an archangel run around unchecked." Dean said softly.

"You're not messing with her." Gabriel warned. "She's our sister."

"Then find her. She's dangerous." Dean stated.

"We can't find her ourselves." Chuck called, opening Dean's laptop.

"Let's help them Dean." Sam suggested. "If we had another sibling that was missing and brought one of us back, I'd want to find them." Sam tried to convince his brother. "Point taken." Dean sighed. "We'll help you."
