Cuse, Lindelof and the Kim's reaction to The Candidate

Says Cuse: “There will be very little debate at the end of this episode that [Fake Locke] is evil and bad and has to be stopped. The main narrative reason for him killing our main characters is to establish how much of a bad guy he is and to clearly identify him as the antagonist rolling into the end of the series.”

Lindelof recognizes that there’s something “brutal” about killing Jin and Sun just one episode after their long-awaited reunion — which, he says, is exactly what made the lovers such an apt choice for making a statement about Fake Locke’s malevolence. “At least they got to die in each other’s arms, so they’d have some sense of victory,” he says. And Sayid? Lindelof explains: “Sayid’s entire season-long arc has basically been, if you tell him that he is evil, you can convince him he is evil. But if you tell him he is good, maybe you can convince him he is good. We basically decided that in a moment of pure instinct, if he did something, if he sacrificed his own life in favor of saving the other people’s lives, that would convey to the audience, ‘This guy was actually a good guy.’”

The good news for fans of Lost and fans of Jin, Sun, and Sayid in particular is that they are technically still alive — in the Sideways world. “Still, it’s bittersweet,” Yunjin Kim told me in a recent interview. “They were kept separate for so long, and then they came together to die together.” She found it “beautiful” that Sun and Jin were given an end that served as an affirmation of their love and the heroic sacrifices they made for each other. “We’ve come full circle,” she says. “Sun came back to The Island [and] risked her life to save her friends and Jin, and then Jin does the same thing back.” When I asked her how she prepared for Sun’s final Island moments, Kim told this story: “Right before we started shooting, [director] Jack Bender took me aside and told me about story that he read a long time ago, about this woman who was missing her dead husband, and how she had this beach ball that he blew up before he died. Every day she took a little breath from the beach ball. And that really got me right into the emotional core of where I needed to be to play that scene. Can you imagine that woman, taking that breath little by little every day, just to feel her husband’s presence?”

Daniel Dae Kim’s thoughts on the end of Jin and Sun? “They were the Romeo and Juliet of the show, and the fact they didn’t have a happy ending does make me sad,” says the actor, who then expanded on the greater significance of the deaths to the show — but I’m afraid sharing his insights (including his take on the fate of Ji Yeon) at this point would be a bit too spoilerish. What was it like shooting his watery demise? “It was pretty difficult that day,” says Kim. “Shooting in water is never easy. But the crew was considerate and made the water warm for us, in more ways than one. Let’s just say certain members of the crew who were in that water for a very, very, very long time without ever leaving. I’ll just leave it at that.”
Now that’s evil.
