It's lost it's magic. You are spot on about Nancy, the mixed race baby but also Trixie's gay brother would not be so open about his sexuality! Being gay was illegal back then. I couldn't be bothered to get to the end of the episode. I've lost any interest in sister MJ (she has been a dull back story for years and to focus an Xmas special on the death thoughts of an elderly woman really is a stretch). They have stopped concentrating on the mother's and the stories of real people, which is typical of todays writers and the over woke BBC in general trying to re-write reality, the show is suffering because of it. What on earth the point of Nurse Crane even being in the episode, complete waste of a decent actress.
