Dean Winchester: To tell you the truth, I don’t think Dad’s ever been to Lost Creek.
Sam Winchester: Then let’s get these people back to town and let’s hit the road. Go find Dad. I mean, why are we still even here?
Dean Winchester: This is why. This book. This is Dad’s single most valuable possession. Everything he knows about every evil thing is in here. And he’s passed it on to us. I think he wants us to pick up where he left off. You know, saving people, hunting things. The family business.
