The line between the living and the dead blurs on Halloween. Two of the house's previous residents give the Harmons decorating advice.

Tate comes face to face with his past, and Ben and Vivien are haunted by a new houseguest before Halloween night comes to an end.

The man in the rubber suit is revealed.

Vivien gives birth. Tate and Violet attempt to rid the house of some of its ghosts for good.
