Comedy: Catastrophe, C4, 10pm

Never again will we be able to sit down on the sofa, excitedly waiting for a brand new episode of Catastrophe after tonight. This is the last one, ever. Sharon and Rob arrive in Boston for a holiday, only to receive the tragic news that Rob’s mum Mia has passed away. Under pressure, the couple need to negotiate with an estranged family member and a “grief vampire”, while Rob has a tempting, but complicated offer from an old friend. Rob Delaney (right) co-stars alongside Sharon Horgan.
