A/N: Please review and tell me what you think.
"I didn't know you had a daughter!" Cas said, more surprised than happy. "Where is she now?"
Dean paused before he replied, "Emma was an Amazon. She's dead now though. Emma came to kill me and Sam shot her before I got to know her."
Sam looked down regretting the time he killed his niece. He did not want to kill her but he did. One, because Emma was going to kill Dean and two, to show Dean how he felt when he killed Amy.
Benny turned to Lilith. "Wait… If your sister was an Amazon, are you one too? Do you even know what they are?"
"I know what they are. I'm not one though. Lydia ran away from the Amazons and joined our family when I was 9. Lydia was a big sister to me. I guess she went back to her real family when I came to this timeline. Hey, can I meet 'me' from this timeline? I'm still alive, right?"
The others exchanged worried but also sad glances.
"Excuse us for a moment," Sam said. Everyone but Lilith moved towards the bookshelves.
They huddled together to discuss quietly whether they should tell her what she did.
"I think she deserves to know," Sam expressed his opinion while Cas and Dean nodded in agreement.
"But she'll freak out if we tell her," Benny whispered, "and if she's anything like you Winchesters, she'll never forgive herself."
"Sorry Cassie but I agree with Benny," Gabriel crossed his arms and shook his head.
"Well, it's three against two. So, we will tell her and besides, it's not really her fault. She hasn't even done it yet!" Dean defended Lilith because he knew what it felt like to feel responsible for people dying, even though you know it was not your fault.
"Yeah, says the guy who wanted to kill her when she first arrived," Gabriel scoffed.
Dean opened his mouth to speak but he could not think of a comeback. "Shut up, Gabe!"
Castiel stepped forwards. "Err… Why don't we just say that she did some bad things and ask her if she wants to know?"
"Jeez Cassie. When did you become such a genius?" Gabriel was shocked. He pointed at Sam and Dean. "Especially when the only people you talk to are these idiots."
"Hey!" Sam pointed at Gabriel. "Don't call me an idiot, Gabe! I got into Stanford pre-law."
"Huh. Really?" Gabriel threw his hands in the air. "Fine! Only Dean's the idiot."
Benny shouted, "Guys! Going off topic. C'mon Lilith is waiting."
Dean moved his chair and sat next to Lilith. "You did some pretty bad things. We can tell you everything but only if you want to know."
"Sure. I mean, how bad can it be?" Lilith shrugged.
"Bad enough that we had to kill you."
"I still wanna know. Even it traumatizes me forever. I should pay for what I did."
"You haven't done it yet."
"Then maybe if I know about it, I can stop it from happening when I get back to my timeline."
"Ok. Lilith, the Devil, Lucifer, took you to Hell and turned you into a demon a long time ago. The worst kind of demon - White-eyed demons. Lucifer was trapped in a cage and you killed hundreds of people." Sam paused to see how she was taking this. Lilith had a shocked expression on her face and her eyes filled up with tears.
"Hey, none of it was your fault. You weren't yourself. I know how you feel. I had special powers that I lost control of and hurt so many people, including Dean." Sam recalled his time using his abilities and drinking Ruby's blood to give him power.
"Sam killed you and in turn, opened Lucifer's cage, releasing him into the world." Dean explained. "But don't worry, as Sam said, it wasn't your fault."
"I-I'm so, so sorry." Lilith began to cry and ran straight to her room.
Cas was about to follow her but Gabriel grabbed his arm. "Give her some space, brother. It's a lot to take in."
