I find it interesting that the KC mob guy managed to actually scare Marty in his office. We haven't really seen Marty like that since Del. Not that he's a tough guy but he's been through so much shyt he's basically desensitized to it. The whole season he wasn't phased by either the Snells or the Cartel, whenever someone threatened him he was like. But for some reason Cosgrove made him shyt his pants.
I think it's a result of Marty's breakdown after he bodied Mason. Dude started acting funny since.
I'm glad he that oxyhead thot tho. I bet most viewers had no sympathy for her but after what happened to Mason, I wanted to see her get a good ending.
