4. Give the computer work the intruder cannot finish
Spock attacks a different part of the problem by ordering the computer to calculate pi to its final digit. Because the task cannot be completed, the instruction occupies the system and undermines Redjac’s ability to use it effectively.
The tactic works alongside McCoy’s intervention rather than replacing it. The doctor reduces the available fear, while Spock contests control of the machinery. Each officer contributes a different solution to the same emergency.
The distinction keeps the episode from becoming another story about a captain defeating terror through confidence alone. Survival depends on several people identifying separate vulnerabilities and acting on them. Redjac’s expansion into the ship creates new opportunities for resistance alongside greater danger.
Forcing Redjac out of the computer still leaves the crew with another problem: locating the entity. Its ability to change hosts makes an unexplained disappearance more dangerous than a visible prisoner. The crew cannot assume the threat has ended simply because the computer is no longer compromised.
