I'll second it here that I consider this episode my favorite so far too. While I've been enjoying the show so far, this episode really stepped things up in a lot of aspects.

We get some more neat world-building, Rin gets her time in the spotlight, and we get a fairly unique plot that doesn't involve actively chasing the monster/threat around the entire episode which give us a lot of chances for some down time.
