- Will Foster: We're the sum total of what has happened to us and how we've processed it. That's what makes us us. It's all neurochemistry.
- Mona: Do you really believe that?... That's all I am? Your children? Just pathways, electrical signals, and chemistry? You have kids that love you and a wife that adores you, and we have a scientist.
- Ed Whittle: And if we make a mistake, I need to know you are prepared to terminate.
- Will Foster: We just won't make a mistake.
- Will Foster: [grabs Ed's shoulders with both hands while speaking with tremendous excitement] No, it's not the mind, it's not the brain, Ed. It's the body.
- Ed Whittle: The body.
- Will Foster: [grabs the back of Ed's head] It's so obvious, so elegant, so simple!
- Ed Whittle: [nervously chuckles] Whoa! Hey man, let's, uh, pump the brakes on the crazy train, alright?
- Will Foster: [preparing to transfer Mona's neural imprint to her clone] Ready?
- Ed Whittle: Has that ever mattered?
- [Will smiles]
- Will Foster: [after getting in the car] The Foster family ferry to fun town is ready to sail.
- Zoe Foster: Yay!
- Sophie Foster: Really, Dad?
- Matt Foster: Actually...
- Mona: Hoist the mainsail, Ahab.
- Ed Whittle: It's been five days. You didn't think that anyone would notice your entire family was missing?
- Will Foster: I've had a lot of things on my mind, Ed.
