The shifter was strangling Sam. Sam was hitting at him pretty ineffectually. When he stopped, the shifter smiled. The best part was when they finally accepted their fate.
"Hey!" he heard behind him.
He stood up and spun around and encountered the real Dean pointing a gun at him. He had no doubt that it was loaded with silver bullets. He thought about lunging at him or picking up Sam as a shield, but in the end decided to willingly accept it. He had the thoughts, memories, and feelings of everyone whose skin he had ever taken. It was beginning to overwhelm him.
