I would like to present the esteemed members of the jury an analogy:
Do you remember this episode? Appointment in Samarra.
Do you remember Dean Winchester’s dialogue following the above scene?
“Well, you know, I’m, uh. I’m no germ freak, but…“
Dean Winchester is not a germ freak. He said so. He said so himself. There is no way that Dean Winchester could have a phobia of germs. The proof is right there.
Dean Winchester actually thinks of himself as not a germ freak.
