Des goes to Penny's new residence in London; she answers the door, but she says she is trying to make a clean break from him. She is obviously very angry and doesn't want to talk.

But he persuades her to listen. He tells her he needs to have a phone number for her that won't change, because he will need to call her in eight years. He won't use the number until then: "December 24, 2004 -- Christmas Eve. I promise." She gives him the number and he memorizes it.

On the freighter, Sayid gets a ship-to-shore patch through, but they only have limited power. Des calls and Penny answers; they are overjoyed to speak with each other. Penny tells him she's been looking for him for three years, and that she got the message from Charlie that Des was alive. "I'll come back, I promise," Des tells her. The connection gives out, but Des gives Sayid his thanks: "It was enough." His constant, Penny, is still there; now he can cope.

Back on the Island, Dan's going through an old physics notebook. One page is filled with a scribbled note to himself: "If anything goes wrong, Desmond Hume will be my constant." This message from his past makes Dan look strangely hopeful.
