It’s what I thoughtDoctor Whois really good at doing, illuminating these bits of history.
Yeah, I figured the Doctor probably has met those figures before.
The thing aboutDoctor Whohistory episodes is that there are always aliens involved.
That title is a little bit of a misnomer.
The worst thing about Partition in this episode can’t be the actual monsters.
How are you guys thinking about the Doctor’s headspace as she figures out her new gender?
That is one of those situations.
This episode focuses a lot on Yaz and her family history.
Yeah, that’s probably one of the hardest things about writing the show.
It’s something Chris always drives us to check that we’re doing.
Keeping them active and doing lots of hopefully fun stuff is a part of the challenge.
It’s just always something that sat at the heart of me.
Everything I’ve ever written, that’s sitting at the heart of it.
When I look at the times around me now, there’s polarization.
That’s the kind of thing that very quickly breaks families and breaks communities.
How did you approach that?
I find that there’s a slight myopia around World War II.
I think people tend to forget that quite easily.
The leadership of people in India had different views.
I find that to be a really under-explored thing, especially the feelings.
I hope this episode is like a springboard.
