You mean the derelict hut they went into hold their hands and try to send the spirit back to hell? It was dark and really scary place. One of those where I wouldn't want to stay any longer than I would have to.The haunted house that John had to walk through at the end was great
It went back to its human shell (that catatonic dude in the mental healthcare centre that John visited mid-way through the episode) and that's why we see that dude going all ragey and throwing things at the end and needing 2 hospital staff to restrain him.I kind of didn't get what happened at the end. Did he banish the spirit and it went back to hide inside the human shell?
Apparently, this was supposed to be Episode 2 to coincide with Halloween but they had to switch episodes because they decided to introduce Zed earlier after deciding not to continue with Liv.A little late in the year for a halloween episode, but the "demons running through kids in fancy dress" trope is always fun! Haunted house was another horror trope, but done nicely with the animatronic creatures giving John a few shocks!
