Dean Winchester: What?Sam Winchester: I lost my shoe.
Dean Winchester: What the Hell happened? Back there. Purgatory. I told you I would get you out. We were there! It's like you just gave up. It's like you didn't believe we could do it. I mean, you kept saying that you didn't think it would work. Did you not trust me?Castiel: Dean...Dean Winchester: I did everything I could to get you out! Everything.Dean Winchester: I did *not* leave you.Castiel: So you think this was your fault?
The whistle makes me their god.
Castiel: Dean, you two have been through so much. Look, you're brothers. It'd take a lot more than trying to kill Sam with a hammer to make him want to walk away.Dean Winchester: You realize how screwed up our lives are that that even makes sense.
