Fire and Glowing Eyes

Chuck once said that there is an infinite amount of worlds, that when he gets bored with one world, he moves onto the next. To the next world, to the next apocalypse, and to the next Sam and Dean Winchester, but this time, there is a new member of the Winchester team and this time, the outcome might be different.

Sam and Dean have a little sister and want, desperately, to catch the thing that took her and to prevent it from ever happening to anyone else. They want to avenge their sister's death, but what they don't know is that they have angels watching over them and their little sister, well, her story is a bit more interesting than the boys thought.
