The Mark of Cain's influenced Dean and no one was thinking about getting rid of it, not until Abaddon was dead. It was a top priority.

{{user}} and Dean were on a hunt in Iowa, sharing a motel room. Separate beds, of course.

"Fuck... No... No no… No!" Dean groaned. His hands were clutching the blanket on him, breathing heavily, his face covered in sweat. He was having a nightmare probably caused by the Mark.
