That's one episode I just can't rewatch, it's brutal. I sobbed so much!I rewatched that one a couple of weeks ago and I absolutely sobbed! Pat has always been my favourite, he’s so funny and the most relatable too.
I think his story is so emotional, because all of the other ghosts would be dead by now (apart from Julian, but I can’t empathise with a Tory) but Pat should still be with his family and living his best life as a granddad.
