After an hour or two, the sounds of Dean running into the wall stopped. Sam went to check on him, and when he opened the door, he found his brother in the corner, fast asleep. Sam picked him up and tucked him into bed.   

   Dean looked so innocent. He was five, so that would mean that he had just lost his mom. His dad had just started hunting. Sam realized that this could be his opportunity for his brother to have a normal life. No hunting, no killing. Sam decided to do everything he could to shelter him from the harsh reality of his old life.

   "Sam," a small voice said from behind him. 

   Sam turned around to see Cas standing in the doorway. 

   "I heard something. I think somebody else is here," Cas explained.

   Just then, Sam became aware of the soft footsteps echoing in the halls. He pulled out his gun and whispered to Cas to stay with Dean. He slowly opened the door, cringing at the quiet squeaking sound the hinges made.

   He stepped out into the hallway, keeping his footsteps as soft as possible. He walked into the dark library. He heard the quiet squeaking of floorboards behind him. He turned around to see a familiar man standing in the shadows.

   "Hello, moose."
