When a witness gets angry at someone in “Sleepy Hollow,” she can summon a powerful demon in the form of her imaginary friend. In Season 4, episode 9, Molly (Oona Yaffe) was angry at her mother for keeping secrets from her and chose to (again) unwittingly summon a monster. Fortunately, Jenny (Lyndie Greenwood) and Molly’s mother Diana (Janina Gavankar) were able to get rid of the demon before it harmed any one.

Last week’s episode also revealed a crucial piece of Malcom Dreyfuss’ (Jeremy Davies) plan: He intends to be a father figure to Molly. She is also an important part of his future.

What will happen in “Sleepy Hollow” Season 4, episode 10?

Team Witness deals with yet another monster. According to the official synopsis, one of Diana’s mentors will be targeted by a horrific monster. This demon is hungry for destruction. She decides that the team must channel all their power toward stopping Dreyfuss and his evil plan.

Meanwhile, Malcom and his lackey Jobe (Kamar de los Reyes) have a breakthrough on a project which team witness may not yet be aware of.

The promo of the upcoming episode, titled “Insatiable,” reveals that the monster-of-the-week resides in the walls! The demon also has a puzzle box. Jenny informs the team that if they can find the box, they can lure him and trap him.

Ichabod Crane (Tom Mison) tries to solve the puzzle box but he seems to be struggling in the video. It’s a good thing Jenny was a master at solving the Rubik’s cube.

In other news, “Sleepy Hollow” continues to dip in terms of ratings. Friday’s episode of the supernatural series drew an abysmal 1.9 million viewers and a 0.4 demo rating. This is a new series low for the Fox show. At this rate, there may not be a Season 5.

“Sleepy Hollow” Season 4 airs Fridays at 9 p.m. EST on Fox.
