When Keith is invited to watch Anita's nephew perform in a concert, he tries to wriggle out of it, paranoid that the boy - who has Down's syndrome - has a crush on him. At AA, fellow member Marianne mistakenly imagines Keith fancies her. So when her beloved cat is diagnosed with cancer and Keith tries to help, a drunken Marianne thinks he's making a pass at her and begins to strip off.

At Keith's AA group, fellow member Marianne is discussing her strong beliefs in God. She also mentions the emotional intelligence of her cat, Chairman Meow, whom she says speaks to her. Keith notices Marianne is wearing a Cross, but she mistakenly believes he is looking down her top.

At home, Keith tries to get out of going to a concert in which Anita's nephew Paul, who has Down's syndrome, is playing. Later, he tells Richard he does not want to go because Paul always gropes him and he believes he fancies him.

Meanwhile, Chairman Meow is sick and Keith is prompted by fellow AA member, Linda, to help Marianne take him to the vet. The news is not good, however, as Chairman Meow might have cancer. Marianne is devastated.

Keith later finds Marianne's Cross in the car and sees it as a sign from God. He takes the Cross back to a very drunk Marianne who, in a spiral of destruction, offers to sleep with Keith and starts to undress. Can Keith stop her from doing something she would live to regret, and will Chairman Meow survive?
