This season may have brought to light Sam's anger management pitfalls, but once again Dean shows how wrath is done. For one, don't kill the most precious in the world being to Dean right in front of him. You'll be awarded with what Randal coined the "I Will Burn A Hole Through Your Fucking Soul StareÂ®." And a promise that "when" (not if) he comes back, he's going to be pissed. I would have dropped the shotgun and crapped on myself while running away screaming. I hope we get a scene in season six where he delivers on that promise.
