Ruby Sunday: watches the man who traumatized her get a happy ending while being gaslit and abandoned by her best friend, but it's all okay in the end because she has a baby brother to take care of.
Belinda Chandra: starts off strong-willed, ready to challenge the Doctor on his bullshit, but completely loses it over the course of the series to the point where she barely blinks an eye at the man she said was "dangerous" torturing a man, then ends up locked in a box for most of the finale and eventually has her entire life rewritten to become a single mother.
The Rani: entire plan revolves around the fact that she's mad that Time Lords can't have babies anymore.
Anita: shows up six months pregnant because she was so broken-hearted by finding the Doctor with someone else that she hooked up with the first guy she met.
Kate Stewart: nearly loses her goddamn mind because her boyfriend that randomly spawned into existence died.
And people actually think that RTD would do a better job writing the 13th Doctor than Chibnall did?
