Catastrophe

Everyone gathers for Des's funeral. Mia arrives from America and develops an odd friendship with Carol before taking up residence at Rob and Sharon's, greatly annoying both of them. After Chris's threats, Fran gets dumped by her boyfriend, and she gets very upset, and knocks on Chris's door, and punches him in the nose. Rob picks up a drunken Sharon from a bar, and they head home. However, Sharon decides she wants to order some pizza, so Rob drops her off. While Rob looks for a place to park, his car gets hit by another car. Although bleeding, he is still conscious, and confesses to Sharon that he has been drinking again, and will fail the breathalyser test that the police will give him, due to the accident.

Sharon's parents visit from Ireland and have a strained introduction to Rob. More health complications create stress for them both, and Rob's secret friendship with Chris explodes in his face.

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.
