This penultimate episode of the second series of Catastrophe tonight sees Sharon deciding it's time to return to teaching, although her meeting with the head mistress becomes more of an outpouring of her grief. Elsewhere, Rob feels awkward around Olivia due to her indecent proposal while Dave's life continues to spin out of control following his split from Catherine - be great if those two nutheads worked it out by season's end! Also tonight, Sharon's brother Fergal fails to repay the money Rob secretly lent him, undoubtedly leading to a whole load of awkwardness.
