[Bridge]
(Uhura is screaming in terror before collapsing across her console. Chapel is standing rigid by the Captain's chair.)
SPOCK: Must I make an example of you, too, Helm?
(Kirk, Mulhall and McCoy enter.)
SPOCK: Pain, Captain. And you, my dear?
(As Kirk and Mulhall double over, McCoy dashes to Spock's side, ready to inject him.)
SPOCK: Fortunately, Doctor, I know every thought of every mind around me. See? Take the hypo from him. And inject him with it.
(But she injects Spock/Henoch instead! He leaps from his seat.)
SPOCK: Fools. I'll simply transfer to another place, another body. Sargon! No, Sargon, please. Let me. Let me transfer.
(He falls to the floor and his victims are freed from their pain.)
