Sleepy Hollow fans are sharply divided into Team Abbie and Team Katrina factions, but will Ichabod (Tom Mison) have to choose sides too?

"There's seeds of doubt that have been planted already between Ichabod and Abbie (Nicole Beharie) already. So the obvious question that Abbie's going to ask is, 'Do you want to find an ally or do you want to find your wife?'" Mison says in the exclusive behind-the-scenes look at the Fox drama below  "There's a lot of mistrust that they may have to overcome," Beharie adds.

Meanwhile, as Katrina (Katia Winter) remains trapped with Headless — who earned himself major brownie points by letting Ichabod live last week — she'll have to make some pretty tough choices herself. "If she lets him believe that there's a chance they may end back together again, he may end up giving her information about what the bad guys are doing that would be really valuable," executive producer Alex Kurtzman says. "So at what point does she lose herself to the reality that she has to immerse herself in?"
