Alright let's see:
Agony: organizes a buddy system investigation with easy communication and safety measures. Then flips of the ghost.
Thesis: Is determined to not go in the house but gets dragged into an expedition by his friends. Gives in and tries to get to the root of the haunting
Duenna: Opens some windows dusts and makes the place nice. Ghosts think she's cool.
Motif: tries to free the spirits from eternal torment but probably hurts himself so bad wandering around this rickety old house that the ghosts take pity and try to free him from their house.
Sequel: Paranormal show dumbassery ensues.
