Abbie (Nicole Beharie) and Ichabod (Tom Mison) will find themselves asking for help from their archenemies in the upcoming episode of "Sleepy Hollow."

In "Incommunicado," TV Guide reports that a supernatural occurrence will take place in town that no one will see coming. This will force the Witnesses to seek the help of their "natural enemies," which may pertain to Pandora (Shannyn Sossamon) and The Hidden One (Peter Mensah). The last time Ichabod saw the pair, they pushed Abbie to sacrifice herself to save her sister and the entire town.

Teaming up with their adversaries will be a bitter pill to swallow, but Abbie and Ichabod will have no choice. In the promo, it appears that it will be Ichabod who will approach The Hidden One with an offer to work together. The centuries-old god, however, will demonstrate his disapproval by hurling the Witness in a cabinet. Abbie will come to his rescue by asking Pandora to help her convince her lover to free Ichabod.

The clip shows the two ladies having a stare down, with Abbie telling Pandora that they will have to find "another way" to approach the problem. The scene cuts to Jenny (Lyndie Greenwood) telling her sister that a hookup with Pandora spells disaster. Abbie responds by saying they do not have a choice. The next scenes show them fighting a woman sporting long horns and another one with a bone-white monster face.

Meanwhile, Jenny and Joe (Zach Appelman) are experiencing problems so early in their relationship. Joe fears that he will hurt Jenny when the monster inside him awakens. Last episode, the two succeeded in securing a piece of Pandora's magical box, but the incident caused Joe to have doubts about himself. Will Jenny be able to convince him that their love is worth keeping?

"Sleepy Hollow" season 3 episode 15 airs on Friday, March 18 at 8 p.m. EST on FOX.
