Castiel feels guilty for what he did to the Novak family
Supernatural is always the fastest hour on TV but this episode was especially stunning in how quickly it got to the point and then drove it home – with a hammer!
What happens when you confront Dean Winchester with deeply felt emotions? Well he doesn’t handle it too well and he turns it around and lashes out. He’s so out of control and afraid, he can’t see straight, so he’s going to say anything to Sam to get him to back off.
Sam knew he needed sleep after staying up the better part of two days, but he couldn’t get Bobby’s letter out of his mind or keep the tears out of his eyes whenever he heard his voice in his head, the words playing over and over again.
