"Sleepy Hollow," the new-mystery adventure on Australia's Channel Ten, has put Ichabod Crane (Tom Mison) and Abbie (Nicole Beharie) on a path that they have to travel, together. Abbie cannot turn the clock-back and turn a blind-eye on Mr Crane, the way she did on her sister Jenny.

Jenny is in an institution. According to the sneak peek of "Sleepy Hollow" Episode 3, "For the Triumph of Evil," Mr Crane visits Jenny. Abbie's relationship with her sister is revealed. The viewers of "Sleepy Hollow" will find out what had happened in the forest when they were school-girls and what did Abbie and Jenny see -- the demon foce.

In the sneak-peek clip, Mr Crane can be seen telling Jenny, "I've seen demons in the woods." Jenny asks Mr Crane to hush it up otherwise he will be also locked-up in the institution. Jenny also reveals that she is in the institution because she talked about what she saw that day, while Abbie is out because she decided to keep quiet. Mr Crane is seen questioning Abbie, "You turned your back on Ms Jenny."

If a Bad Witch was the dark spirit in the second episode of "Sleepy Hollow," the dark spirit in the new episode is called "Sand Man" The Sand Man is someone who makes people confront their past. "The Sand Man comes to you in your dreams and shows you what you the thing that you did wrong," according to the sneak peek.

Since Abbie turned a blind eye on her sister, the Sand Man will continue to torment her in her dreams if she does not correct that. It looks like Abbie needs to confront her own inner demons and she will be doing that in "For the Triumph of Evil." If Abbie is unable to do that and correct the wrong, she is going to die.
