In an attempt to restore some 'goodness' into the plot he goes to Colin's flat to see his young wife Veronica, who mistakes his declarations of love as a sexual advance and invites him to seduce her.
The action of the play is broken up by two mock television commercials for breakfast cereal ("Krispy Krunch") and dog food ("Waggytail Din-Din"): both of which feature Denholm Elliott's character Jack Black acting, and justify his claim to the psychiatrist that the adverts present an idealistic and "pure" world view.
The play's final turning in on itself as one long commercial for tranquillisers[2] sees Jack dressed in a medic's white coat in a television studio, quoting the "Epistle of St Paul to the Philippians".
Jack's paranoia about his predicament is intensified by his awareness of the camera, which he frequently addresses, either to demand that it stops following him, or to ridicule the audience ("I can picture them now [...] Munching away on their telly snacks, the corrupt zombies").
