D.A. Howard: Mr. MacGyver, how would you describe Zito?
Skinner: Well, we're going to keep fighting. You've made too much progress to give up now.
Zito: Oh, be assured, I never give up, Dr. Skinner.
Zito: I hated to cut short our little discussion about evil. It's a subject close to my heart.
Zito: Do you actually think you're qualified to judge what is evil?
MacGyver: I just call it as I see it.
Zito: I'm an expert on the subject. One day I'll educate you. A lesson in evil, you might say.
The German episode title is "Die Lehre des Bösen", meaning "The Science of Evil".
