'Sleepy Hollow' Spoilers: 'Heartless' Features A Succubus

Tonight's episode of "Sleepy Hollow," which airs at 9/8c on Fox, will feature another horror-inducing creature from classical literature, the succubus. The episode is titled "Heartless" and it also includes more details about the relationship between Katrina (Katia Winter) and Ichabod (Tom Mison) .

However, the focus of the episode is going to remain fixed on the succubus Lilith (played by Caroline Ford). She has been brought to Sleepy Hollow by Henry (John Noble), who is actually the son of Ichabod and Katrina, and is now the Horseman of War. Being invited by Henry means that Lilith has a lot of power to wield. She does so by attracting men who desire something in their heart. She then proceeds to feed on their life force and destroy them.

IGN notes that the succubus' skill set allows her to "play on people's darkest and deepest desires and then becomes what they desire to seduce them."

Henry seems to have taken her specific skill set into account when bringing her to town, knowing full well that there a number of "love triangles" which she can take advantage of.

Mison also noted to IGN that Lilith targets Halwey (Matt Barr) because he is attracted to Abbie (Nicole Beharie ) who is currently working closely with Ichabod, while Ichabod has feelings for both Katrina and Abbie.

Elsewhere in the episode, Katrina and Ichabod will try to settle some of their problems. It will also see Katrina helping Ichabod and Abbie track down the succubus and Henry revealing the contents of the glass jar and how it ties into Moloch's plan to come to earth.

As for Abbie she will end up having a huge verbal duel with Katrina about the fate of Henry. During this argument Ichabod will find that he is stuck between two determined women. It remains to be seen if the trio will end up saving Henry from Moloch's clutches or end up destroying both.
