Seemingly back in the swing of a fully functioning relationship, Rob and Sharon receive a very surprising dinner invitation from estranged couple Fran and Chris. Meanwhile, Fergal travels back to London to give an update on his unsatisfactory family life in Spain. Sharon has a check-up with a less than empathetic doctor where it's revealed that she's now pretty low in the egg department. And Rob's dark secret is uncovered by Chris.

Rob and Sharon are in Ireland to say goodbye to Sharon's dad. Rob's utterly irrepressible mum Mia travels from America to pay her version of respects. With Fran reeling in shock, and Rob still unable to find the right time to talk about his almost-secret collapse, all roads are leading to a dramatic series finale.
