I assume this is the show:

New series from MoE’s creator, potentially set in the same universe..
Intriguing episode, with so many layers. Also, there are so many characters that I haven't fully connected them all yet after only a first viewing. Part of it is that everyone seems to know Mare.
My wife and I liked the first episode. Plenty of layers and relationships that long-form storytelling on TV can introduce and hopefully resolve by the end.
