Another Nephilim

Prologue

Sam was slowly climbing the stairs. His head roared with all sorts of thoughts. His mother was gone, Cas was gone, Lucifer (hopefully) was gone either. Unfortunately, the hunter had no time to process all of this. When Dean knelt beside his best friend's body, Sam immediately made his mind: There was Satan's son in the house in front of them, and someone needed to take care of him.

The hunter ran into the room where Kelly gave birth, but all he found was her body - Sam expected her face to be full of pain, after all childbirth is one of the most painful experiences in the world, but she wasn't. For some reason her face was so calm, relieved. Sam knew that it was complete the opposite of what his face must've look like in the moment. He looked at the floor. There were numerous footprints on it - they looked as if the person which made them was literally burning. They were far too big to belong to a newborn, and there seemed to be too many of them - but if kid was just learning to walk, it was ok.

Sam took a deep breath and he gathered his courageu to follow the footsteps. Younger Winchester faced with numerous of monsters in his life, but it was different. It was Lucifer's son, kid of the creature which has been torturing Sam by decades. Castiel believed that baby wasn't evil, but the hunter needed to see for himself. Following the footsteps, the man headed for the children's room, which was intended to belong to Jack. Clearly, he felt safer there. That was good, it looked like a human reflex.

But when Sam entered the room, he froze. There were two reasons for this: First, the kid gave him the most terrifying smile he has ever seen. Moreover, which was much more surprising, he wasn't alone.

Jack stared at the man with interest. He wasn't sure who he was: Mom met him several times for a short time, so he couldn't be sure if the man was good like Castiel, or evil like Dagon. When human came inside, he seemed to be concerned, so Jack smiled. A smile is a human friendly gesture, so Jack expected it to calm him down. But looking at the face of the man Jack could tell, that he was just more scared. Jack frowned - did he do something wrong? Then he noticed that the man's gaze was no longer directed at him.

Boy instinctively peeked at his sister: A girl of the same height held a hand on his shoulder, unsure whether to approach the stranger. She was a step behind her brother, looking at him, unsure what to do. Jack knew he needed Castiel, he was supposed to take care of them.

"Father." Nephilim spoke, hoping that stranger can bring his father here. Castiel would protect both of them.

"No no no no." A man answered quickly, apparently not understanding the boy's intentions. "I'm not your father."

"Father." Jack repeated, still hoping he would understand.

"I'm Sam." A man answered, measuring both of them with an uncertain look. "And you're Jack, right?" Boy nodded, so Sam looked at girl hidden behind her brother. "And who are you?"

"Jack." The girl spoke in a gentle voice. Apparently this man did not expect her here. Jack knew that thanks to him - he protected her, hid the girl from a dangerous world.

"Like..." Whatever Sam was about to say didn't make it because someone hurried in the corridor.

"Sammy?" Another man arrived inside, with a worried expression on his face. This man was equally confused as the first one, by seeing two nephilims, but in opposite to the one with longer hair, he didn't take a while to understand what was going on. Instead, he pulled out a gun and fired at nephilims. Jack immediately covered his sister with all his body and was shot in the shoulder. Second bullet didn't reach him, because the other man stopped his friend.

"No!" The one with the longer hair yelled, clearly trying to protect Jack and his sister, but young nephilim couldn't take the chance. Before anyone could do anything else, the boy screamed at the men. They both hit the wall and then fell to the ground. Jack didn't kill them - he could feel the life force from them - but he didn't want to. The threat was averted and that was all he needed.

"Jack." His sister spoken silently, so boy turned around to her. She looked worried at the wound on his arm, but when it healed immediately, she calmed down. Jack smiled soothingly at her and she smiled back in the moment.

"Father." Boy said, and his sister nodded. They didn't know too many words yet, but they spent the last five months in only each other's company, so they didn't need too many of them to communicate. They needed to find father. Then everything would be alright. For a moment they shared comforting smiles and after a while they took hands and moved towards the exit from the room.
