Captain Spock: My father says that you have been my friend. You came back for me.
Kirk: You would have done the same for me.
Captain Spock: Why would you do this?
Kirk: Because the needs of the one... Outweigh the needs of the many.
Captain Spock: [begins to remember] I have been and ever shall be your friend.
Kirk: Yes. Yes, Spock.
Captain Spock: The ship... Out of danger?
Kirk: You saved the ship. You saved us all. Don't you remember?
Captain Spock: Jim... Your name is Jim.
Kirk: Yes.
Sarek: At what cost? Your ship...your son.
Kirk: If I hadn't the cost would have been my soul.
McCoy: Yes! Genesis! How can you be deaf with ears like that?!
