Never mind the moss-covered rusty ship, with its serious Creepy Basement vibe, but the protagonists hear something inside the panic room, knocking on the door.

- The dolls from the second episode.
- A.J.'s experience under the tree. Made all the more frightening by the fact that there's really nothing supernatural about it.
- What happens to Manny. Dear God, poor Manny.
