The episode was written by Damon Lindelof and Elizabeth Sarnoff and directed by Karen Gaviola.
The woman is Cassidy, whom Sawyer trained to be a grifter and all of whose money he stole in the flashbacks of a previous episode.
Cassidy asks Kate why she didn't want the police to be called; later, over drinks at a bar, Kate explains that her stepfather was a bad man, so she killed him, escaped from the US marshal who arrested her, and now is back in Iowa to talk to her mother.
Locke tells her he does not want to go home; he explains that he made a strong case for her but then they told him who she was and what she had done, he knew that they would likely not forgive her.
Back at the barracks, Kate hears noises outside, looks through the screen and sees the Others packing to leave.
The canister pops open and gas starts fuming out, knocking her out cold.
Juliet's yell of pain attracts the smoke monster, and they quickly run into the roots of a banyan tree for cover.
The Monster roils up in front of them, and Juliet's face is lit up by a series of bright flashes of light.
Juliet jams the setting into the red zone, enabling the previously disabled pylons to send a powerful sonic wave to anything that tries to pass between them.
Back at the beach, Hurley tells Sawyer that after the Nikki and Paulo situation with the diamonds, the camp is going to vote on whether or not to "banish" him.
Hurley says there are benefits to living as part of a society and suggests he make amends to fix things.
He apologizes to Hurley for calling him all those names, is nice to Claire and gives her a blanket for the baby and tells her that Aaron looks less wrinkled since the last time Sawyer saw him, and partners with Desmond to hunt for boar and provide food for the camp.
Hurley explains that with Jack, Locke, Kate and Sayid gone, Sawyer is all they have, and is the de facto leader.
Sawyer sees how happy he made people and attempts to keep the good vibes going, even offering to hold Aaron for Claire.
Kiele Sanchez (Nikki Fernandez) and Rodrigo Santoro (Paulo) are no longer credited with the starring cast.
