Almost as much of a pain in the ass as most demons." Perhaps even more, sometimes. They had nearly gotten Dean killed several times over since raising him from Hell and they were constantly getting in the way. The last strike had been when they swept Dean away to torture Alastair. If not for Sam rushing to the scene in time, Alastair would have murdered both Dean and Castiel. Fortunately, with a bit of focus and drink of demon blood, Sam had been able to both torture Alastair and destroy him all with a wave of his hand. It was fun out-doing the torture master. It really, really was.

Lifting it up, Sam peered at his reflection in the silver. He dropped the pot onto the floor when he saw what was staring back at him. Black eyes. Just like a demon.
