Author's Note: Okay, I finished this chapter in no time. I was that excited! And oh so fun! But yeah, if Cain seems OOC, well, it's AU, and in the bottom author's note, I'll explain. WinchesterRifle, you can skip that. But overall, enjoy! SHOUT OUT TO Sarahhh3 again because she's nice.

Sam Winchester couldn't sleep. He had been ordered by Dean to try to avoid moving in his sleep, and to not sleep on his stomach. Yeah, like I'd do that. Even if I wanted to, it hurts way too much. Since he apparently had insomnia for the night -probably from sitting down all day, thanks, Dean- he decided to think of how their meeting with Cain could go. In thirty minutes, he had come up with quite a few possibilities. Most aren't good for us. He closed his eyes, and felt a chill on his skin.

"Hello, Sam Winchester," Sam opened his eyes. A young man in an ancient style tunic, with dark hair and dark eyes, stood in front of him. He looked somewhat familiar.

'Who are you? I feel like I should know you." Sam racked his brain for a name to match the face, but it never came. If I had met him before, I would definitely know him. Sam looked around where they were. It was nothing but darkness. Okay, he definitely isn't human...

"Well, you're trying to find my brother Cain. I'm also your ancestor. I'm Abel." Abel, the younger brother of Cain who was killed by him. Also the older brother of Seth, Sam's encyclopedic mind told him.

"How and what are you doing in my head?" I really dislike having people in my head after all my hallucinations of Lucifer. And, considering you spoke with him...

"Yes, I am aware the Devil can be quite...charismatic. But also cruel." For a moment, Sam heard sympathy in Abel's voice. It passed though.

"You didn't answer my question." Sam's voice was hard as steel, but Abel merely laughed.

"Oh! I am very proud of my descendants! I like you, Sam, otherwise I would not be here. So I will answer your question: I am here to warn you, and as to how...I've been around for a good while, I know a few tricks." Sam didn't care so much about the how anymore, but the why intrigued him.

"What are you here to warn me about?" Sam had an idea, but wanted confirmation. Abel gave him an 'I like you' look. A paternal way, of course. Would it be grand-paternal way, seeing as he's my...forget it.

"I'm here to warn you about your upcoming meeting with my brother. How you might survive it. I'm sure Cain told Dean of our tragedy, but I have a side, too. I was naïve, and thought I could convince Lucifer and God to...come to an agreement. Lucifer somehow tricked Cain into thinking I was destined for Hell. Who knows, I may have been. So Cain stabbed me, and I died. Afterwards, he went somewhat insane with grief and guilt, and put a curse of fratricide on the Blade. He gave it to many pairs of brothers, all who had a protective older brother -Dean and Cain- and a younger brother who adored him, but strayed from the straight and narrows -you and I- it was his way of making sure he wasn't the only one who acted that way, his way of saying 'All older brothers act the same.' Cain seems to conveniently forget his curse makes them do that act. But nevertheless, he is my brother and I love him. When Colette happened...I was beside him, though he did not know. I have watched over Cain for millennia, and witnessed what he did to your brother. I have always wanted my brothers' pain to cease, but this is not the way to go about it. I will not allow him to damn Dean to Cain's fate. You must persuade Cain to take the Mark back and kill himself with Blade." Sam looked at Abel in a new light, as he absorbed all this information. He looked his newfound ally, his ancestor, in the eyes, and asked,

"How can I convince the Father of Murder to commit suicide?" Abel's brow furrowed, as if taking offense to the title of his brother being used in his presence. Just like me and Dean.

"Sam, I know you are a great orator. Together, you and I can find a way to stop history from repeating itself." Sam looked into Abel's dark eyes, a little unnerved by the eery similarity they had to his father's.

"I could remind Cain of what he did, and of his morality. I could tell him I talked to you. Would that work?" Sam formulated that plan in seconds, so he doubted it would work. But Abel nodded.

"It would. But Cain would never believe I came back down. He doesn't want me to leave, and so refuses to think I would." Both younger brothers put their minds to work. Abel spoke first. "I will tell you my last words to him: 'Brother, why?'" Sam gazed at Abel, those words echoing in his head. He could picture it now. Somehow, reading it from the Bible just doesn't have the same effect. It doesn't describe the pain of betrayal and agony that your brother betrayed you, and killed you...

Abel cocked his head. "You're peculiar. I've not come down often, and was mainly focused on Cain, but you actually tried to understand us. Thank you. Would you like to see how it happened?" Abel touched his fingers to Sam's forehead, and the scene unfolded. The dark room transformed into a field of wheat, barley, and rye, with Cain and Abel strolling through the fields.

"So, why did you invite me here? It is beautiful and I have been delighted throughout our time, but why? I must tend to our flocks." A younger Abel, maybe twenty at max, inquired, his dark eyes filled with trust and questions directed at his brother. Sam saw Cain slide the Blade into his hand, though began to circle his brother as to hide it.

"Lucifer told me of your talks. You are destined for Hell, Abel, and therefore leave me no choice on how to save you." Cain stepped forward, and, like Lucifer and Dean, stabbed his younger brother in the stomach. Abel, however, gasped out, 'Brother, why?'. Sam saw the agony of betrayal, the horror of what Cain had done, and the sorrow of it all in Abel's eyes before he died. Gabriel, Abel, and I, we're more alike than I though. I know I had that look in my eyes, I felt like that when Dean...

When Abel fell lifelessly to the ground, his blood watering the plants Cain tilled, Sam looked at Cain. Cain's eyes were filled with tears. "Abel, I am so sorry. It is all I could do to save you." Cain looked at the bloody Blade in his hand. "It is all I could do."

The vision abruptly ended, and Sam looked straight into Abel pain-filled eyes. "Sam, I have tried to save every pair of brothers, but I can appear only to my bloodline. You must convince my brother, otherwise...you'll die, Sam."

Author's Note: YAY! And, I actually looked up in the Bible where Abel was killed, and what Ancient Israelites grew, so flamers can just not. One of the reasons why Gabriel and Lucifer come up so much is because that is how I imagine Sam being stabbed by Dean, and Abel by Cain, soo...As for anything not matching the show...well, this kinda went AU, and also, I am not allowed to watch Supernatural, and rely on the CWTV website and the wikia, and I missed the Cain episode. So if it said Abel made a deal with Satan...well, AU is my defense. ANYWAY! Hope you enjoyed and please review or favorite or follow or whatever!
