Hearing of Spock's refusal to relinquish command, and having recovered sufficiently to be able to walk, Kirk returns to the bridge to relieve Spock and order him to the sickbay, intending to turn command over to Mr. Scott. When Uhura picks up another encoded transmission from inside "Enterprise" and traces the source to the brig, Kirk decides to stay on the bridge. When Thelev is searched, it is discovered that one of his antennae is fake and conceals a small transceiver.
