Catastrophe
A new acquaintance becomes increasingly friendly with Rob, while Sharon dabbles in a new hobby.
Rob's newly religious sister Sidney visits from the US, and a child's accident at school reveals a surprising teacher-pupil rapport to Sharon.
Sharon and Rob decide to get on a fitness drive. When Sharon visits her less-than- sympathetic local GP it dawns on her she's not in the peak condition she imagined.
Rob is pretty unenthusiastic about celebrating brother-in-law Fergal's 40th birthday, while Sharon comes face-to-face with her mum's 'new man'.
Sharon is unsettled by a strange moisture patch at school, while Rob's big boss visits London and takes a close interest in his career. Fran and Chris make a major decision.
In the final episode, Sharon and Rob arrive in Boston for a family holiday only to receive some tragic news about Rob's mum, Mia. Under pressure, the couple need to negotiate an estranged family member and a 'grief vampire', while Rob has a tempting, but complicated offer from an old friend.
