Corrected entry: Spock has been known to say that Vulcans don't lie. But in this episode, he backed up McCoy who was trying to spare Kirk's feelings. When asked by Kirk about the final taped orders he left them, Spock said that "The crisis was upon us and passed so quickly there wasn't time to view the tape." A bald faced lie.
Corrected entry: At the beginning of the episode the bridge crew is looking at the viewing screen as the Defiant draws closer. By the time Capt. Kirk says "The Defiant", it is totally obvious that it's a starship. However, when Kirk says "The Defiant", the bridge crew gives quite a reaction as though they had no idea what this thing shaped a starship was until Kirk clued them in.
