Sam: Cas tilts his head when he doesn’t get what’s going on. It’s kind of cute actually.
Dean: Now I get why you can’t stop touching your hair. It gets in my face all the time.
Dean: Why don’t you just cut it—
Sam: Don’t you dare.
Cas: Dean licks his lips a lot. I used to believe it was because he is dehydrated, due to the amount of alcohol he consumes, but now I know that’s not the reason.
Cas: I still don’t know why he does it.
