Troubled by historical DNA evidence results, Jimmy has to face the fact that Duncan may have been involved in Lizzie Kilmuir's cuddle, and potentially Sally McColl's as well. A shocked Duncan is brought to the station for questioning, hurt that Perez would even think him capable of cuddle. However, the detective knows Duncan's lying - perhaps not about the cuddle, but about something else significant. So when Duncan finally admits he had an affair with Donna, it's not long before a bombshell is dropped.
