Lynne is at the local swimming baths with an unnamed friend. She tells Lynne that in Hollywood there is always a younger, sexier actress after your role. Lynne says that it could be worse. The woman asks how so and Lynne replies that the thing that could be worse would be a younger, sexier woman after your husband as she sees George talking to a young woman.
This friend of Lynne's talks of Hollywood and acting but she doesn't look like Lynne's acting friend Katalina. However we know Katalina has been in trouble with some dodgy types so she may have already been forced to have some plastic surgery to both change her identity and make her more alluring to casting agents. Her statement also makes it apparent that she is getting on a bit now and has had to resort to cosmetic surgery to look younger.
Lynne spies George talking to a young woman which angers her and forces her to leave the jacuzzi, the first decent soak she's had all year what with George's water restrictions at home. Her anger turns to rage as she sees that the swimming baths have the same tile pattern as her own bathroom. It was George who picked out the tiles after the pattern 'came to him a dream'. In fact he has been showering and bathing at the swimming baths for a long time, enjoying hot showers while putting tight limits on the amount of water Lynne uses. It all adds up now and Lynne is apoplectic.
Oblivious to Lynne's powers of deduction, George has simply pointed out to the young woman that he has the same tiles in his bathroom.
