1)The Partition of India is another era I know little about. This season makes me want to read more history.
2)"Tread softly. You're treading on your own history."
3)"We can't have a universe with no Yaz!"
4)As with "Rosa", we see that human malice is worse than any fictional aliens.
5)And another one where the Doctor didn't so much have a threat to fight, as she just had to let things happen.
Overall: Another moving historical episode.
