Nikola Tesla: Mr. Angier, have you considered the cost of such a machine?
Robert Angier: Price is not an object.
Nikola Tesla: Perhaps not, but have you considered the *cost*?
Robert Angier: I'm not sure I follow.
Nikola Tesla: Go home. Forget this thing. I can recognize an obsession, no good will come of it.
Robert Angier: Why, haven't good come of your obsessions?
Nikola Tesla: Well, at first. But I followed them too long. I'm their slave... and one day they'll choose to destroy me.
Robert Angier: If you understand an obsession, then you know you won't change my mind.
