"Sleepy Hollow" Season 4 came as quite a surprise for both the fans and the cast of the show, as neither had any idea that the show would be renewed. For the next season, Ichabod Crane will be accomplishing his mission of finding the next Witness. He is said to become a different man than what he used to be.
Season 4 Mission
"Sleepy Hollow" Season 4 will be airing on January 2017. However, prior to this, spoilers have started to leak for the premiere episode, titled "Columbia." Crane and Jenny, played by Tom Mison and Lyndie Greenwood, respectively, would be back on their mission. The two will then be looking for the Witness, while Crane gets a new partner for his quest. Diana Thomas, to be played by Janina Gavankar, would be his new partner in "Sleepy Hollow" Season 4
Abbie Mills is reportedly making an appearance in "Sleepy Hollow" Season 4, whose pilot is said to not be as emotional as the previous season's finale. The first episode will also feature a big revelation, making Crane eventually realize that he actually underestimated the amount of evil involved in his "Sleepy Hollow" Season 4 mission.
New Partners, Lost Partners
In the earlier season of "Sleepy Hollow," Crane had already lost Mills. The death of his partner would definitely fire his motivation in completing his mission. Crane's new partner in "Sleepy Hollow" Season 4 is Thomas, who would also be in the same situation. Thomas originally had no knowledge of the supernatural, and just also lost her partner.
When the two first meet in "Sleepy Hollow" Season 4, things would get quite a bit chaotic, as Thomas proves himself to be a skeptic. However, things would definitely go around and the two will end up working smoothly after all.
One of the more interesting spoilers suggest that two characters would be hugging it out warmly in the premiere of "Sleepy Hollow" Season 4. These two could very well be Thomas and Crane, who would be reluctantly consoling each other. "Sleepy Hollow" Season 4 Episode 1, "Columbia," will be airing on Friday, January 6 on Fox.
