RAND: Then he kissed me and he said that we, that he was the Captain and he could order me. I didn't know what to do. When you mentioned the feelings we'd been hiding, and you started talking about us.
KIRK: Us?
RAND: Well, he is the captain. I couldn't just. You started hurting me. I had to fight you, and scratch your face.
KIRK: Yeoman, look at me. Look at me, look at my face. Are there any scratches?
RAND: I was sure I scratched you. I was frightened. Maybe
KIRK: Yeoman. I was in my room. It wasn't me.
RAND: Sir, Fisher saw you, too.
KIRK: Fisher saw?
RAND: If it hadn't been. I can understand. I don't want to get you into trouble. I wouldn't have even mentioned it!
KIRK: It wasn't me!
FISHER: It was you, sir.
KIRK: Do you know what you're saying?
FISHER: Yes, I know what I'm saying.
MCCOY: Back to that bed, bucko. Come on, let's go.
SPOCK: You can go now, Yeoman. (Rand leaves) There's only one logical answer. We have an impostor aboard.
