Supernatural Rarepair Shipfest 2013

There's a darkness in Sam, a "temper issue," as Crowley describes it. Most of the time he manages to keep it under control, but there are moments, especially where his loved ones are concerned, where Sam's wrath gets out of control. Whereas most people tend to just get out of the way when this happens, Crowley has found that the best way for Sam to get the rage out of his system is to goad him into taking it out on Crowley.
