Plot:

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.
