Dr. Zin and Korchek in “Double Danger”

I want that formula!

Yes, Doctor.

An increase in the dosage and your space crew becomes totally without will, puppets as it were. Interesting?

Very interesting, Dr Zin!

Such pills dropped in the water supply of a major city...would reduce the inhabitants to a flock of sheep awaiting instructions.

Ooh, a brilliant plan, Dr Zin!

I have a brilliant opponent in Dr Quest. But this time I shall win!
