"If you hold back anything, I'll kill ya. If you bend the truth, or I think you're bending the truth, I'll kill ya. If you forget anything, I'll kill ya. In fact, you are going to have to work very hard to stay alive, Nick. Now do you understand everything I've said? [Nick nods head] Because if you don't, I'll kill ya. Now, Mr. Bubble and Squeak, you may enlighten me."
