Return to Tomorrow
Super beings take control of Kirk, Spock, and Dr. Mulhull's bodies in order to build androids to inhabit. But they are not without human weakness.
Ah, the ol' body switch. While the super beings are pretty predictable (one's bad, they're pressured to stay, they can't live among humans, etc.) the device does allow our cast to stretch their skills. Shatner gets to go way over the top with the pompous Sargon (as opposed to usual sorta-over the top), while Nimoy is afforded a rare chance to play a total slimeball. (And emote.) We don't know much about Anne so comparisons can't be made. Bones would have made an interesting host, since De Kelley's a fine actor, but he's quite understandably opposed to the whole thing. The others might have done well to heed his warnings rather than buy into Kirk's swelling speeches. The rules of body switching change constantly, making for an unsatisfactory climax; by the end they can inhabit glowing spheres, humans, half a human, androids, the ship, and oblivion. A wonder they're having trouble finding a home! They choose the last option, since they're too dangerous to stick around. And they're kinda annoying. No one will miss them.
Spock Saves the Day: Spock and Nurse Chapel inject the hypo that forces Hennock to flee Spock's body.
Oops: The Vulcan might have been a bit gung-ho with this body-switching thing, since his "guest" is evil.
Developments: While Spock himself only occasionally hints at his physical superiority to humans, Hennock announces right away that his body is he best. It's unknown whether the Chapel brainwash is accomplished through Spock's powers or Hennock's, since both are capable. (Though the Vulcan seldom manipulates humans.) The "pain" is all Hennock's doing. Spock can't be blamed for being sheepish after "sharing consciousness" with Christine.
