Blair and Nyx Grey are sisters who are not so human. Nyx is just like Sam Winchester- and Blair, well she's just out there. During the first chapter, the girls meet Sam and Dean when both are hunting the same thing. After Nyx pulled the demon out of the plane- Questions rise and answers become scarce. Blair doesn't trust other hunters after one in particular hunter tries to kill her sister- John Winchester. The sisters don't know that Sam and Dean are John's children at first- So you can just imagine what is bound to happen.
