The Federal Bureau of Investigation (FBI) will be busy juggling several cases all at once in the upcoming episode of the FOX series "Sleepy Hollow."

In "Sins of the Father," TV Guide reports that Atticus (Bill Irwin), one of Pandora's (Shannyn Sossamon) vindictive minions, will return to Sleepy Hollow. His arrival will mark the start of several mysterious occurrences that will baffle Abbie (Nicole Beharie) and her colleagues at the Bureau. While his boss lady is away planning her next move with her lover, The Hidden One (Peter Mensah), Atticus will keep the Witnesses from forgetting that something big is coming at them soon.

Meanwhile, Jenny (Lyndie Greenwood) will finally snap and confront Ezra (James McDaniel) about their broken family. This will bring up memories from the past that are best forgotten. In January, showrunner Clifton Campbell shared how Ezra's story has gotten "twisted." He said that Abbie and Jenny's father was portrayed as someone who left his family, but that's not necessarily true.

"I think the hardcore fans have always wondered about Dad. There was a picture painted of him early on that was the guy who ran off, who couldn't deal, and who fled. It's very nice to find that that's not necessarily true, and the part of it that is true is much more realized in the back half of the season," he told TV Line.

According to co-executive producer Albert Kim, Ezra has always been "a figure of mystery," even for the Mills sisters. His reappearance in their lives in season 4B will be an eye-opener, as it becomes clear just how much has been "missing from his perspective." With Jenny's decision to finally confront her father, the time may have come for her and the viewers to know why it took quite a while for Ezra to show his face to his daughters.

"Sleepy Hollow" season 3 airs Fridays at 8 p.m. EST on FOX.
