A scene from “Sláinte”

Kieran Reilly: You can think whatever you want about me or where I come from, but I got a sense of loyalty. I was raised with the understanding that you don't go against someone unless they go against you or one of your own.

Flack: So you killed a man based on some twisted sense of loyalty you had toward Byrne and your neighborhood.

Kieran Reilly: My world has laws and a code, just like yours. Break it, and you're done.
