Christian: This is the place that you all made together so that you could find one another. The most important part of your life was the time that you spent with these people. That's why all of you are here. Nobody does it alone, Jack. You needed all of them and they needed you.

Christian: Not leaving, no. Moving on.
Jack: Where are we going?
Christian: Let's go find out.
