No one would do anything but just be happy. There would be no reason to do anything.

Captain Pike and his crew are lured to Talos IV by a race capable of creating powerful illusions.
Original air date: October 15, 1968
The Magistrate: We had not believed this possible. The customs and history of your race show a unique hatred of captivity. Even when it's pleasant and benevolent, you prefer death. This makes you too violent and dangerous a species for our needs.
Vina: He means that they can't use you. You're free to go back to the ship.
Capt. Christopher Pike: And that's it. No apologies, you captured one of us, threatened all of us.

The Magistrate: She has an illusion, and you have reality. May you find your way as pleasant.
