Fandom seems pretty split on whether he said 'neurotically' or 'erotically.' I haven't rewatched yet, so I don't know. My mom and I both heard erotic though.

How was Cas just taking off his tie so fucking hot? IT'S JUST A TIE! And yet, it was the hottest thing ever.

I hope Cas is okay. I'm sort of sad that this means I probably wont get hilarious Gabe n Cas fun times next week,
