Spock Amok

With the Enterprise under repair at Starbase One, Spock worries that T'Pring thinks he is becoming too human. Their plans for time together are interrupted when Admiral April asks Pike and Spock to help win over the R'ongovians, a people choosing between the Federation, the Klingons and the Romulans. Spock and T'Pring try a Vulcan mind meld ritual meant to deepen understanding, but it accidentally swaps their katras, leaving each in the other's body. Spock must handle T'Pring's work with Vulcans who have rejected logic, while T'Pring, in Spock's body, joins Pike at the negotiations, which succeed when Pike realises the R'ongovians mirror whoever they meet. Meanwhile Una and La'an, branded fun-killers after catching crew playing the unofficial game Enterprise Bingo, set out to complete it themselves. M'Benga and Chapel eventually restore Spock and T'Pring to their own bodies, and the couple come away understanding each other a little better.
