Kirk was deeply troubled by the loss of Grant, who he excused for the incident as being "young and inexperienced." He was later at a loss of understanding as why Grant had to die, noting that they neither lied to nor violated any of the Capellan's customs. McCoy explained to Kirk that it was "because he was drawing a weapon on their guest," Kras, to which Kirk replayed the scene, "Grant looked up, saw a Klingon, made a purely instinctive defensive move."
Kirk later apologized to McCoy for snapping at him, to which McCoy conceded that he knew what it means to Kirk to lose a crewman. This bothered Kirk more, knowing that "that's only one down, Doctor. There's over 400 more up there in orbit."
Later, when Kirk and company were introduced to High Teer Akaar, he stated to the leader, "first, I must protest the killing of my crewman." Akaar, however, was confused by this statement, inquiring, "if it was your man, wasn't it his privilege to die for you?" (TOS: "Friday's Child")
