I feel like this episode should have been interspersed with other episodes. It was only 37 minutes and she left in episode 2, not to be seen until episode 8. I feel like the Kier stuff is probably the weakest part of the show for me, but the episode did provide necessary world building. Also, we could have kept Harmony as part of the story for the entire season rather than forgetting about her for 6 episodes. This was the weakest episode of the season, but I get why it was necessary to the story.
