When Dean said to Sam "Look, until I jam that blade through that douche bag's heart, we are not a team. This is a dictatorship. Now, you don't have to like it, but that's how it's gonna be." he killed it, he finally started relying on himself and stopped worrying about constant-whining Sam, he needed to stop giving that kid the attention.
Overall great episode and fantastic season!
