“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.“
Dean's core is a hurt child with a thick shell of bravado, so we figured he'd connect with kids. Then Jensen Ackles made it sing with gruffness and warmth, so we kept doing it. (Eric Kripke, December 21, 2023)
Sometimes I like to think about Dean and Cas always casually drinking from the same bottle, without really noticing the implication of it all because it has just become second nature to them, no matter where they are, and I go a little insane over it!
