Ana-Lucia's in a bar. Try to contain your surprise. The dude who shot her is over by the pool tables saying goodbye to a buddy before slinging his jacket over his shoulder and leaving the bar. Ana follows him (naturally, she finishes her drink first).
Out in the parking lot, McCormack heads to his car. Ana-Lucia calls to him, and he turns around. "I know you?" he asks. Close-up on Ana-Lucia, but the motion of her shoulder and arm suggests she's just drawn a gun. "I was pregnant," is all she says, and she fires three times. Jason didn't appear to have even noticed or reacted to her gun at all. I can see how he got the drop on her last time. He drops like a sack of mangos and Ana-Lucia approaches his body and pops three more shots into him.
Back on Craphole Island, Sayid says, "What happened to him?" Did he miss the flashback? Ana-Lucia says McCormack was never found. She gets up and picks up the makeshift machete stuck in the ground. As the music builds, she walks up to Sayid. OH MY GOD SHE'S TOTALLY GOING TO KILL HIM. She swings the machete and cuts the rope holding him to the tree. Maybe Michael gave her tips on freeing someone in the riskiest and scariest way possible. Then she drops the knife and the gun in front of Sayid. "Go ahead," she says, telling him to pick up the gun. "I deserve it." He grabs the gun and scrambles to his feet. "What good would it be to kill you, if we're both already dead?" Oh look, here comes my lunch back up. I sincerely hope this is a fantasy sequence involving Sayid and Ana-Lucia on Hokey Dialogue Island. No? It's the real deal? He walks over to Shannon's body (he no longer has the gun in his hands), gathers her into his arms, and starts sobbing. Ana-Lucia turns away.
Sawyer's on his bunk, struggling and convulsing, while Kate looks over him. "Hey, can you hear me? You're gonna be okay. You're gonna be all right," she says, stroking his face. "You're home." Sawyer mutters something about the other guys laughing at him for not making People's sexy list. "Even Dominic made it," he whispers, and rolls over.
