"I don't know who you are. I don't know why you did it. If you are looking for a free score I can tell you I don't have money to afford that, but what I do have are a very particular set of skills. Skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my Marty back now that'll be the end of it. I will not look for you, I will not pursue you, but if you don't, I will look for you, I will find you and I will Marty your ass."
