Up until this point in the series, Class just kept impressing me, and Nightvisiting is a clear stand-out episode that really caught my attention from beginning to end.

This is just a wonderful blend of horror and character work. The script is almost entirely built around the guilt these characters feel being used by a monster. It's done really well - where the monsters are able to be intimidating without relying on effects to make something scary or gross, nor jump scares or any other kind of horror gimmick. It's just this haunting sense that of course it would be hard to deal with these lost loved ones playing up on your feelings.

Tanya's character, who up until now hadn't had much to do, really gets to shine here - but Ram also shines here a bit with a more recent grief. I like how his dead girlfriend isn't just tossed aside or forgotten.

This is also just a well shot episode with lots of memorable scenes and visuals. I really liked Nightvisiting overall.
