Olivia: Etta's not gone, Peter. Windmark didn't take her.
Peter: Yes, he did.
Olivia: No, he didn't. She's still here with us.
Peter: She is dead.
Olivia: She saved my life today with the bullet she brought to us. She's alive inside us. And there's nothing that Windmark can do about it because the love that we can share with her now is invulnerable to space and time, even to them. And I know that our hearts are broken and that it hurts, but that's what makes us human.
Peter: Emotion is our weakness.
Olivia: No, Peter, it's our strength, because it's the one thing that they don't have.
