- Daniel Faraday: You knew all along - you knew this would happen. And you sent me here anyway...
- Eloise Hawking: Who are you?
- Daniel Faraday: I'm your son.
- Daniel Faraday: I studied relativistic physics my entire life. One thing emerged over and over--can't change the past. Can't do it. Whatever happened, happened. All right? But then I finally realized... I had been spending so much time focused on the constants, I forgot about the variables. Do you know what the variables in these equations are, Jack?
- Dr. Jack Shephard: [Chuckles] No.
- Daniel Faraday: Us. We're the variables. People. We think. We reason. We make choices. We have free will. We can change our destiny.
