We Need to Talk About Kevin

Dean re-emerges from Purgatory, but he isn't alone. He heads straight for Sam, but the reunion isn't exactly what he thought it would be. Sam drops everything to join his brother, but leaving the life he had grown to enjoy turns out to be harder than he imagined. Dean and Sam look for Kevin who has managed to escape Crowley's grasp, but things come to a head quickly when Kevin tells them what it is that Crowley wants.
