Jamie hires an ex-boyfriend, Sherman (guest star Rick Rossovich), to paint the apartment and is a bit annoyed when Paul is not concerned by the prospect of her old flame being alone with her. When Paul comes home from his job, he finds Sherman and Fran together in their bed having sex, because Fran is stressed over her move-out from Mark's apartment. So, Paul talks to Mark about their marriage. Jamie and Paul try to get them back together, but they decide to split up.
