Dr. Finn: Couple's counseling helps married people, such as yourselves, discuss and resolve conflicts with the goal of improving your long-term relationship. I'm here to guide that process.
Bortus: Will we select our own weapons?
Dr. Finn: No, that's not how it works.

Dr Finn: Do either of you understand why you're here?

I am led to understand that you are a failure in the practice on mating.

Bortus
