Dean and Sam in “Unfinished Business”

Dean

You know I finally get why you and Dad butted heads so much. You two are practically the same person. I mean, I worshiped the guy, y'know. I-I dressed like him, I acted like him, I listened to the same music. But you are more like him than I will ever be. I see that now.

Sam

I'll take that as a compliment.

Dean

You can take it any way you want.
