I thought that with Delia's bit with the student doctors Tizzy. It would make sense wouldn't it.
They completed copped out of the adoption storyline, and I agree I felt more sympathy for Dot than Marnie. Maybe it's because she had that hope and then it was taken away from her, there were parallels with Gloria in some ways. I kind of hoped that character would have a show down with the dickhead doctor for taking so long to do the necessary. Poor woman, and women like her.
I'm liking the Turners, even though some of their lines and scenes are clunky AF. Might rewatch the series where Sister Bernadette trades in Big JC for Dr T.
