For a good bit I thought we were dealing with the Nightsisters, the way they talked about being witches, but they bear very little resemblance to the Witches of Dathomir, physically, in their fashion, and in their practices, not to mention they're not on Dathomir.
It seems right now like they're an entirely new Force cult or religion, which I found absolutely fascinating to watch. Shame we didn't get to spend more time with them, but if we get a Jedi POV of those two days, maybe we'll learn more.
Good, subtle use of de-aging tech in the episode to make the actors appear a decade and a half younger. The kids were great, and I liked getting to explore a little of their old life.
Really liking Sol so far, and it was nice to see a bit more of Indara.
I expect we'll be back in the "present" next week. Hopefully we'll see more of the masked Sithy apprentice.
