Dean Winchester: Things aren't just black and white out here. All you have is a case in front of you, like Hayden. A few months ago, there was this kid, this psychic. She was killing people, but she didn't mean to hurt anyone. She was being abused. So we gave her a second chance because it was the right thing to do.
Mick Davies: Well... that's your luxury. We have a code.
(Flashback showing Mr. Ketch killing the psychic girl)
(Mick arrives with Cas to the cellar where Toni was holding Sam hostage and Dean came to rescue him...)
Mick: I powered down all the wardings in this shack so your attack dog could come in. I reckon you could finish me off without breaking a sweat. Am I right?
Castiel: I don't sweat under any circumstances.
