Back on the island, Richard, Miles and Ben are heading to Ben’s house to get his stash of C4 to blow up the plane. While there, Zoe and Widmore arrive. Widmore explains that after the freighter was blown up, Jacob visited him and explained what he must do. Widmore orders Zoe to go sink their boat and she leaves. Widmore explains that he brought Desmond to the island because of his immunity to electromagnetism. Zoe calls up on the walkie explaining that Locke has arrived on the island. Widmore orders her to return and when she is on her way Widmore says they all need to hide in Ben’s closet. Miles leaves on his own while Ben and Richard decide to confront Locke; thinking they can either buy time or get him to leave. With Widmore and Zoe in the closet walk outside. The black smoke slams into Richard and tosses him into the woods. Ben sits and Locke approaches and says that there are some people he’d like Ben to kill and in exchange, Ben can have control of the island after Locke leaves. Ben accepts and tells him that Widmore and Zoe are in his closet. Locke promptly slices Zoe’s throat and tells Widmore that if he tells him what he wants to know he won’t kill penny when he leaves the island. At first Widmore doesn’t seem to trust him, but relents and tells him of Desmond. When Locke asks why Desmond, Widmore doesn’t want Ben to hear. Ben turns around and he whispers inaudibly into Locke’s ear. Suddenly Widmore is shot numerous times by Ben, with Ben explaining that he (Widmore) “Shouldn’t have the opportunity to save his daughter” and then asks Locke if there are others he wants him to kill.

In the woods, young Jacob appears to Hurley and demands his ashes from Hurley. He takes them and runs away and Hurley gives chase, and comes upon adult Jacob in the woods around a campfire. Hurley brings Jack, Kate and Sawyer to Jacob, who they can now see and communicate with. Jacob explains that he made a mistake when his actions made his brother into the smoke monster and he knew that eventually he’d find a way to kill him; so the candidates have been his preparations for his eventual demise. And that protecting the island is what the others “have all died for.” He says that he must have a successor before the fire burns out; once it does, he is gone for good and “it would be very bad” if there isn’t someone to take his place. Sawyer complains that his life was fine before Jacob brought them there, but Jacob interjects that they were all lost, lonely and broken, like he was. Kate asks why she was crossed out and Jacob explains that it’s “just chalk on a wall, he crossed her out because she became a mother and the job is still open if she wants it”. No one accepts at first, until Jack stands and says this is what he was meant to do and accepts the “job”. Jacob explains that the light is the heart of the island and is what must be protected from extinguishing; which is what MIB wants to do. Jack asks if they’re supposed to kill him (MIB) and Jacob says that he hopes they can. Jacob gets a cup from Jack, says a “prayer” to the water and gives it to Jack to drink; when he does, Jacob says “Now we are the same”.

In sideways world, Locke goes to Jack and explains that maybe fate is what cause his accident and maybe Jack is supposed to fix his spine. Jack accepts (after the uttering of a few familiar phrases).

On the island, Locke and Ben reach the well to see that Des is not there. Ben asks what it was that Widmore said to him about Desmond. He says that Des was Jacob’s “Failsafe” in case all of his candidates were killed; but that Desmond will be useful to Locke now because Desmond can do what Locke has never been able to do, “Destroy the island”.
