Mr. Spock uses his Vulcan telepathic ability to lure her into the cave, where Kirk knocks her unconscious and seizes her control belt.
Their freedom is short-lived, however, and as punishment Rojan orders the Kelvan Hanar to activate his belt, transforming two of the landing team members to small spongy cuboctahedral blocks of a chalk-like substance.
Kirk and Spock decide to try to adapt McCoy's neural scanning equipment into a countermeasure to the Kelvans' paralysis field.
As a pretext for beaming back to the ship, Spock feigns illness by placing himself into a deep trance.
Once the ship has crossed the galactic barrier, the Kelvans reduce ("neutralize") all personnel except Kirk, Scott, Spock, and McCoy into cuboctahedral spongy blocks of a chalk-like substance.
Scott introduces the Kelvan engineer Tomar to the alcoholic beverages such as Saurian Brandy, something "green" from Ganymede and finally "very very very old scotch", McCoy injects Hanar with a "supplement" for Anemia that is actually a stimulant, and Kirk begins a flirtation with Kelinda, provoking feelings of jealousy in Rojan.
