A man never discloses his own character so clearly as when he describes another’s.
I Just Noticed Something Very Interesting About Cas in 6x10
Remember how he was watching porn?
I just realized something about this. Cas did not have a boner while watching the porn.
He only got the boner AFTER HE LOOKED OVER AT DEAN.
Also, DEAN LOOKED DOWN AND NOTICED CAS HAD A BONER. SAM KEPT LOOKING AT HIS COMPUTER, NOT CARING. DEAN WAS CURIOUS. JUST SAYING.
