Jack: Look, you want to get to work, you're going to tell me how you got here.
Desmond: It was three years ago. I was on a solo race around the world, and my boat crashed into the reef, and then Kelvin came.
Desmond: Kelvin - he comes running out of the jungle - hurry, hurry, come with me. He brings me down here. The first thing he does - because there's beeping already - he types in the code, he pushes the button, and it stops. What was all that about, I say. Just saving the world, he says.
Jack: Saving the world?
Desmond: His words, not mine. So I started pushing the button, too. And we saved the world together for awhile, and that was lovely. Then Kelvin died, and now here I am all alone. The end.
