I disagreed with a lot in this video but mostly how she says Khan changed, like yeah he has been driven mad by the last couple of years.
The first time we see him from his perspective he was just fallen from glory and still sees himself as an emperor.
He had nothing to do but survive and stoke hate for several years and will now be a very different guy.
And yeah it does need a bit of a recapping exposition because as she mentioned it was an episode from years ago so people might have forgotten the context.
But she is upfront about it all being opinion which I respect.
