Father? Sam's eyes widened at the word that Jack spoke. They both stared at one another. Jack and Alexandria both stand up naked as Sam takes a step back away from them. He clearly didn't know what he was going to do in a situation like this, with two newborn children of the two most powerful Archangel's who try to poses them. Especially when Castiel had told both Sam and Dean about Alexandria being more powerful than any Nephilim or Cambion.
No, no, no. I'm not your father, Jack. It is Jack, right? And Alexandria? Sam said as his voice shook with fear. He was absolutely petrified and scared of the cousins. He had no idea of who they were like, Kelly or Lucifer. Or Michael or Kaida, who had no idea that a greater demon possessed her. Before any one in the room could speak, the sound of the front door opened and echoed throughout the house.
Father? Jack repeated the question as Alexandria looked at the hunter in front of her out of curiosity. Sam? Sammy? Dean's voice could be heard as Sam's glaze left both of the cousins in front of him, he immediately fires at them. No! Sam quickly tried to stop Dean. But the bullet's missed both Jack and Alexandria completely.
They were both scared and lost. Both of their mother's had warn them both, that the world outside was horrible, painful and cruel. Only for the two to learn and support each other. They never knew it to be happening after they were born.
They began screaming as they used their powers for the first time in their lives. It blasted the windows out of the upper floor of the cabin. Both Sam and Dean appear to be moving in slow motion through out the house and once they stop screaming they are thrown across the wall. Knocking both of them out, the cousins decided to leave before the Winchester's would wake up.
