'Sleepy Hollow' Season 1 Finale Spoilers: 2-Hour Finale to Air Jan. 20, 2014

"Sleepy Hollow" fans can look forward to an all-new episode on Jan. 13, 2014.

The upcoming episode is titled "Vessel," Fox states. The TV network also issued a press release revealing that "Sleepy Hollow" is set to wrap up its first season on Monday, Jan. 20 with a huge 2 hour finale, reports the Hollywood Hills. The show will air its penultimate and ultimate episodes back to back from 8 to 10 pm that evening.

While Fox has not unveiled many details about the episode, actor Tom Mison did drop a spoiler that the finale is a harbinger of even bigger twists to come.

"Every week, there's going to be something massive," he says, promising "a huge climax" in the season 1 finale next year.

"Since we came back from the hiatus, there's been a really strong narrative arc," he added. "It just builds and builds and builds."

Executive producer Ken Olin echoes the actor's excitement, telling TV Line about the narrowing the gap between purgatory and the present-day New York 'burg. "In the finale, certainly there will be a more immediate kind of convergence between the two worlds that will not only involve Katrina and Crane, but Abbie, too," he said.

Executive producer Roberto Orci also revealed to TVLine hints regarding the horseman's return, "This means war." So... can he tell us which one it is? "I just did," the sly series co-creator responded. (Maybe that's what Moloch meant in last week's episode when he warned, "When you know my meaning, war will take form"?)

"Sleepy Hollow" S1E11 airs Jan. 13 and the season finale airs Jan. 20 on Fox.
