- Scott: Perhaps the Vulcans should hear about this.
- Captain James T. Kirk: Mr. Spock, can you be prevailed upon to bring them the news?
- Mr. Spock: Possibly, Captain.
- Mr. Spock: [with a wry look] I shall certainly give the thought all the consideration it is due.
- Mr. Spock: [after McCoy injects him with hypospray] Your action is highly unethical. My decision... stands.
- [He collapses]
- Mr. Spock: What is puzzling you, Captain?
- Captain James T. Kirk: I'm not puzzled, Mr. Spock, I'm awed.
- Dr. McCoy: I'm with you, Captain. She awed me.
