"I don't know who you are. I don't know what you want. ...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 apprentice go 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 kill you."
