Hurley, Jack, and Sawyer arrive at the chopper. Kate is trying to pick the lock of Frank's cuffs while Sayid guards them. There are happy reunions, flirty chat about murder between Kate and Sawyer, and Jack acting like a douche. (By which I mean rather than express happiness at seeing Kate, he just asks her what she did with the baby.) Sawyer notes that Frank is kind of stupid for trying to pick the lock when there's a hacksaw in the toolbox. He starts sawing away while Jack asks Sayid if it's safe on the freighter (pointing out that a body washed up on the beach). Sayid: "It's safe now." Which is when a lesser director might have cut to the freighter and showed us the dangerous C-4. Instead, we stay here and see Sawyer free Frank from his bondage. And then they all get in the chopper and fly away. Hurley wants to be sure that they'll come back to look for Claire after they get everyone else to the boat. Jack reassures him that they will. And as much as this show always jerks us around, I still find these scenes of escape from the island to be incredibly moving.
Orchid station. The elevator arrives and Keamy gets out. D'oh! I guess they should have checked for a pulse. His only weapon is a small knife. He staggers in and calls out for Ben. But this time he reminds him that he's wearing a bulletproof vest, so Ben should really aim for the head. Keamy strips off his shirt. Thanks, show! He shows off the thing strapped to his arm. As pretty much everybody figured out, it's a dead-man's trigger. If Keamy's heart stops beating, the C-4 will explode, killing all kinds of innocent people on the boat. And then Locke walks up behind Keamy. He introduces himself and explains that he has no conflict with Keamy. He's trying to talk Keamy into putting down his knife so they can talk. Keamy doesn't really care to talk. And then Ben emerges from a locker, beans Keamy with a crowbar (or maybe his baton or a piece of rebar), and stabs him several times, while shouting about how Keamy killed his daughter. The dead-man's trigger starts beeping. Locke: "You just killed everybody on that boat." Ben: "So?" Commercials.
Beach. Daniel starts to tell Charlotte something about the boat, but she tells him that she's staying on the island. He explains that if she doesn't come now, she could be there forever. Charlotte: "Nothing's forever." Daniel asks her why she'd stay. Charlotte: "Would it make any sense if I told you I was still looking for where I was born?" Although that's perhaps the clearest thing she's ever said, Daniel tells her it makes no sense. She laughs, and kisses him on the cheek. She says goodbye, and walks away. Daniel walks over to the boat. He meets Juliet on the way, and has already realized that she's also not coming. She tells him that she's committed to staying until everyone else on the beach is safe on the boat. She promises that she'll still be there when he gets back. Daniel: "Right. When I get back." Daniel and six no-name Losties head out to the freighter.
