We open the show staring down the barrel of a gun. Oh, crap; are we supposed to be wearing 3D glasses for this episode? The gun fires several times, perforating a shooting target in a cluster in the head and neck. Ana-Lucia grimly lowers her smoking gun and removes her yellow protective goggles.
Cut to a psychiatrist's office, where a shrink is trying to draw Ana-Lucia out. She cleans up nice. He asks how she's doing. "Well, the family with the screaming baby moved," she says. Did you shoot at them? The shrink says she must be thrilled, but she says it's actually too quiet now. Extra-special fidget-cam close-up of her fingers nervously drumming on the arm of her chair. The shrink takes notice, then asks if she and "Danny" are trying to work things out. She says there's nothing to work out, and that she's one of those people who's better off alone. Well, that's just safest, wouldn't you agree? Shrinky asks how the firing range went, and how it felt to hold a gun again, and it was "good" and "very good" respectively, and he says all these steps count: "You've come a long way since we met four months ago." Ana-Lucia doesn't say anything to let us know happened four months ago that prompted the shrink visits, but I imagine we'll find out before the hour is up.
Instead, Ana-Lucia asks if some unnamed "she" has said anything about when it would be okay for AL to come back to work, and there is some "Do you think you're ready?" and "what do you think?" jousting, before the shrink strolls over to a table and picks up a billfold-y thing, and hands it to her. "Welcome back to the force, Officer Cortez."
Back to Ana-Lucia getting the stink-eye from Sayid after she's shot Shannon. Sayid slowly stands up, and stomps towards Ana-Lucia, only to get intercepted by Eko, and they wrestle in the mud, with Sayid holding his own against the much larger Eko as they both fight for the gun. There is much shouting from the other castaways. Eventually, Ana-Lucia bops Sayid on the back of the head, knocking him out. Michael tries to intervene, and gets a face full of gun from Ana-Lucia. Michael, I'd be careful. She's LAPD. I'm just saying.
Back from the opening break, Ana-Lucia's still got the gun pointed at Michael and Jin while she asks Eko to check to see if Sayid has anything on him. Eko's all, "Whaaa?" and doesn't seem moved by Ana-Lucia snapping that Sayid just had a gun pointed at Eko's neck.
