Spock: "I will go with you, Captain."
Kirk: "No, I need you on the bridge."
Spock: "I can not allow you to do this. It is my function aboard the ship to advise you in making the wisest decisions possible, something I firmly believe you are incapable of doing in this moment."
Kirk: "You're right! What I am about to do, it doesn't make sense, it's not logical, it is a gut feeling! I have no idea what I'm supposed to do. I only know what I can do. The Enterprise and her crew needs someone on that chair who knows what he's doing. That's not me. It's you, Spock."
