Los Camden se sorprenden por la llegada de Mary con su nuevo chico Ben y su hermano policía Kevin, y con su nuevo trabajo de azafata de vuelo que les permite vuelos baratos. Mientras Lucy se acerca a Kevin, Eric todavía se obsesiona con el secreto de Matt y Robbie y Ruthie siguen ayudando a mantenerlo. Eric descuida su cita de asesoramiento con los ancianos Tallridge, cuyo hijo adulto Jerry se ha "mudado repentinamente", pero eso es lo que lo inspirará.

Ruthie wants her bedroom back forcing Robbie out now that Matt will be moving out and Simon gets upset that Matt chooses Robbie to be his best man and Sam and David call for Robbie instead of him. Lucy gets upset that Kevin won't come to Glen Oak for Matt's wedding and Ben decides to propose to Mary after Mary starts giving him the cold shoulder.
