He chases her down in the parking lot, claiming he was going to tell her everything. "You looked me right in the eye, and you lied to me. You made your choice, John. You need his love more than mine!" she says. He starts in with the I choo-choo-choose you, and says, "I was going to --" and then halts himself, like he doesn't want to spoil the big proposal moment. She's opening the car door, and he just completely goes for broke: "Please, Helen. I love you and I want to spend my life with you and, and I can't live without you, Helen, so…" He gets down one knee, takes out the ring. "Will you marry me?"
Fighting back tears, all Helen can do is shake her head, climb in her car (and I'm momentarily distracted by her seatbelt, which is one of those ones that automatically slides on the chest strap when you close the door -- I love those!), and drive off.
Across the parking lot, Cooper's watching the whole thing with an expression on his face like, "Damn, dude." Not that he comes over or anything. He just gets in his cab on retainer and drives off. Something tells me that the $200,000 is no longer up in the motel room.
And then another plane lands on Locke's head.
Back in the hatch, the alarm is going nuts. Locke's yelling for Henry, but there's still no answer. Then the alarm stops, and we hear what sounds like the timer numbers resetting. Out of the woods? Nope. The lights go out. "Please say something," says Locke, in the dark. Nothing. And on come black lights -- and right in front of Locke, on the blast door currently pinning him to the floor, is what looks like a hand-drawn map of the island's hatches in glowing ink. All over is squiggly writing and arrows and such. Great. Something else I won't be able to fully appreciate because I won't buy a television that costs more than my first car, and I don't have Adobe Photoshop at home.
The black lights are on for about 30 seconds; then they flicker and go out, and the regular lights come on again. And all the blast doors come up (giving Locke some pain when the bar at the bottom of the door pinning him pulls out of his leg).
Locke yells for Henry, and crawls into the computer room. "Henry? Anybody here?" He sees the timer is at 107 minutes. He calls again for Henry, who strolls up all nonchalantly from behind. "You came back," says Locke. "What, did you think I was going to leave you here?" says Henry. Pretty clearly, yes. Henry asks if Locke can stand, and he hesitates and then says he thinks so. With Henry's help, he gets up and leans against a wall. "Thank you, Henry. Thank you for not leaving me." "You're welcome, John," says Henry. Remember, Locke, you owe him now -- no matter what.
