That's so like you. This is the man you just called a psychopath, who tried to kill you without permission, and is helping me keep you trapped in a cell back home - a cell, I might add, that you do not escape from for eight months. I'm not sure if you know that part. [He probably shouldn't say that so flippantly, but he's not to best at realizing when he's being an asshole.]

And you want me to feel sorry for him.
