Sophia: Do you know what scares me the most?
Michael: No, what?
Sophia: The letting go... of who I used to be. I knew that it would be painful to follow through on Thomas’ plan, that in order to make room for our people here, to ensure their survival, I would have to… sacrifice some of my principals.
Michael: Well, you’ve taken a huge burden on your shoulders, Sophia.
Sophia: But that doesn’t make what needs to happen next any easier.

Michael: Now I have to go.
Leila: When I was a kid, I was playing with the boys across the street, and they killed a bird. I told you what happened, and you said we were the strongest and smartest things on the planet, so we had a responsibility to protect the smaller, weaker things, because if we didn’t do it, that no one else would. That it was the right thing to do. I don’t know if you remember that, but I do. And I’m looking at you, and I don’t recognize that person anymore.
