Season 6, Episode 1 - Sister Ursula [a rant]
I'm rewatching for the 100th time and I firmly believe that Sister Ursula was the reason Sister Mary Cynthia had a full breakdown.
Sister was doing well when the team left for South Africa and by the time they got back, she was severely broken.
Plus, Sister Ursula looked horrified at the idea of delivering a baby at Nonnatus, and I think she would have been shite at delivering a baby in general. I know she worked at a cottage hospital that was shut down, but some Sisters aren't good midwives and I think Sister Ursula caused very bad things to happen. Not to mention she had zero idea how district visits worked and the difference between them and hospital treatments.
Ugh, I'm so angry at that woman.
