I like this season very much - especially as they go for a bit more serialized plots. I don't mind Trixie's alcohol problems still being an issue - stuff like that does not just magically disappear and I think it was very subtly done. I'm also glad Patsy's love life is still a theme albeit a tragic one. Nice bit of counterbalancing with Fred's courtship by haberdashery. This was definitely Nurse Crane's episode and she owned it - her face when she heard the young nurses giggle after she had left the room was heartbreaking. And throughout the tinker scenes I tried to place that face - I just knew that I've seen the actress play another fierce matriarch. In the end I had to check with IMDB: Mrs S - of course! It's high time Orphan Black returns.
