Star Trek

Spock: Father...
[the elder Vulcan turns and is revealed as Spock Prime]
Spock: I am not our father.
[Young Spock, now recognizing who he is, approaches]
Spock: There are so few Vulcans left. We cannot afford to ignore each other.
Spock: Then why did you send Kirk aboard, when you alone could have explained the truth?
Spock: Because you needed each other. I could not deprive you of the revelation of all that you could accomplish together, of a friendship that will define you both in ways you cannot yet realize.
Spock: How did you persuade him to keep your secret?
Spock: He inferred that universe-ending paradoxes would ensue should he break his promise...
Spock: You lied?
Spock: Ah... I - I implied.
Spock: A gamble.
Spock: An act of faith. One I hope that you will repeat in your future in Starfleet.
Spock: In the face of extinction, it is only logical that I resign my Starfleet commission and help rebuild our race...
Spock: And, yet, you can be in two places at once. I urge you to remain in Starfleet. I have already located a suitable planet in which to establish a Vulcan colony. Spock, in this case, do yourself a favor: Put aside logic. Do what feels right.
[Spock Prime turns and leaves]
Spock: Since my customary farewell would appear oddly self-serving, I shall simply say...
[Shows Vulcan hand salute]
Spock: Good luck.
