Effy's lost her mojo. Mindless sex with Cook no longer satisfies her and things in the Stonem household are becoming intolerable. She resolves to confront her feelings for Freddie but finds him ensconced with Katie. Katie relishes the power she gets being Freddie's girlfriend and puts Effy in her place by inviting her to the party she's organized in the woods only so they can make the most of her car and telling her that Cook is not welcome. Effy sees what a mess she's in and is sickened.
