As the tailies (and Jin, Michael and Sawyer) finally make contact with the rest of the survivors of the crash, they do so in a big way. Shannon is dead, the victim of a gunshot, courtesy of Ana-Lucia. Sayid tries to take it to her, but Mr. Eko proves too much for him and he ends up tied to a tree.
This gives Ana-Lucia a chance to reflect on her life. It turns out that she was a police officer in Los Angeles, undergoing psychiatric evaluation for being involved in an incident where an officer was shot - her. As it happens, she gets to go back to work - for her mother is also her captain. She wrangles her way into a patrol car, but in the first stop, she pulls her own weapon on someone, and when she gets back to the station, they found the guy who shot her. But she won’t identify him, so he goes free. That night she heads out to find the guy, and fills him full of bullets.
While all this is happening, Jack and Kate start to play three holes of impromptu golf for bragging rights, and wouldn’t you know it - as they are playing, Mr. Eko comes out of the jungle carrying Sawyer over his shoulders because Ana-Lucia insisted on using the vines holding the stretcher together to tie up Sayid. Luckily Mr. Eko is not only strong, but has a heart too.
Locke, playing a crossword puzzle in the hatch, is surprised to see what’s happening when Mr. Eko arrives, but he tries to figure out everything that has happened while Jack and Kate take care of Sawyer. Meanwhile Ana-Lucia is persuaded to let everyone go on to the camp, but only in exchange for some supplies - including some ammunition for her gun. Unfortunately, Bernard and Libby don’t have much faith in Ana-Lucia, so they leave - leaving her alone with Sayid.
Michael makes it back to the hatch and starts to take Jack and Locke back to Ana-Lucia, but when Mr. Eko mentions her name, Jack realizes that they met in the airport bar prior to the flight leaving, which just about floors him. Then Mr. Eko agrees to take jack to meet her, but only without guns.
While they are on their way, Ana-Lucia is telling Sayid the story of her life - that she was a cop, and that one night she was on a call when a suspect shot her, and she lost the baby she was carrying. This is when we found out that she killed the guy, but she doesn’t tell Sayid that, only that now she now feels dead. She frees Sayid and asks him to kill her because she deserves it, but he declines, because she is already dead. Instead he goes to Shannon and carries her back to the camp.
