->''"What good would it be to kill you if we're both already dead?"''
-->-- '''Sayid Jarrah'''

In flashbacks, Ana Lucia returns to her job as a police officer after being shot. The suspect who shot her is brought in, but she refuses to identify him and he is released. She later tracks him down and kills him, after revealing that she was pregnant when he shot her.

On the Island, an enraged Sayid tries to attack Ana Lucia for killing Shannon, but is stopped by Eko. Ana Lucia holds the other survivors at gunpoint, and forces Libby to tie Sayid up. Eko takes Sawyer to the survivors' camp against her will so he can be treated by Jack. Jack brings Sawyer into the Swan, where he manages to treat him with Kate's help. Eko tells Jack and Locke what happened to Shannon, and agrees to take Jack to Ana Lucia as long as he doesn't bring any guns.

After a conversation with Sayid, Ana Lucia decides to let him go, and gives him a chance to kill her, but he declines. The Tailies join the survivors camp, and loved ones are reunited: Michael with Vincent, Jin with Sun, and Rose with Bernard. Sayid brings Shannon's body back to camp, and Jack and Ana Lucia have an uneasy reunion.
