Kirk returns to sickbay for further care and finds Spock and Sarek both alert, the surgery an apparent success. Spock speculates that Thelev and the attacking ship were of Orion origin, and the speed and power of the latter were consistent with a suicide mission, with all energy dedicated to attack. Thelev's mission aboard "Enterprise", Kirk and Spock presume, was to sow distrust among the Federation members and weaken "Enterprise" prior to the attack. In support of this theory is the fact that Orion has been raiding Coridan, and would profit by selling dilithium to both sides in a war. Amanda asks Sarek to thank Spock for saving his life, but Sarek shrugs and says that it was only logical. Amanda expresses anger at this harping on logic, and Spock, noting her temper, asks Sarek why he married her. Sarek replies, "At the time, it seemed the "logical" thing to do," and offers Amanda his hand in a ritual gesture of affection. McCoy then firmly orders Kirk and Spock to remain quietly in bed, finally getting the last word.
