No Spoilers.
I'll start with the good. The episode does actually have character progression that makes sense. People finally have conversations that actually matter and overall the episode is *Somewhat* Good. Sean and Julian are a cool part of the episode (and shows Rupert Grint is still doing most of the carrying for this show). However, Dorothy "figures out" something about Leeane because someone made a single statement to her. Like Seanne in the Halloween episode, these characters usually can't figure out things for themselves and someone has to point out the obvious for them to have a "revelation".
Like the description says, the Cult makes a "Bold Move" but here's something I don't think the writers seem to understand: Hurting people in Self Defense doesn't make you a monster, especially if you're outnumbered or trapped. Her getting satisfaction from revenge is the only happiness she can feel BECAUSE of how badly everyone else has treated her. The writers are probably hoping we'll forget that Dorothy tried to kill her and that she was dragged back into the situation against her will.
There's a really stupid twist with the Cult that is completely ridiculous and proves Leeane's paranoia isn't misplaced.
Sadly they're still doing half-finished conversations with interruptions (to extend the runtime) and overdone Tropes. This week it's "Animals sense evil and get hostile" like we've seen so many times already.
