Ichabod Crane (Tom Mison) has a new partner. True Blood alumna Janina Gavankar is set for a recurring role in Fox’s drama series Sleepy Hollow as Diana, a new character who will be introduced in Season 4.

The new character helps fill the void left by the controversial departure of female lead Nicole Beharie who played Detective Abbie Mills and was killed off in a shocking twist at the end of Season 3.

Gavankar’s Diana is described as a single mom and former military officer who’s currently a Special Agent for Homeland Security. She’s got a tough, take-charge personality, punctuated by a wry sense of humor. She also has a softer, more caring side which emerges when she’s with her young daughter. Initially she doesn’t believe in the supernatural, and that creates conflicts with Crane. They also clash because they have different ways of approaching missions: While he’s methodical and research-focused, she’s active and task-oriented, which is reflective of her military training. She rarely talks about the father of her child—a person she cared for, even though she never saw a life together with him—but she’s fiercely devoted to her daughter and will do anything to protect her, an instinct Crane appreciates. After her partner goes down in the line of duty, she and Crane will find common ground in their shared sense of loss. And the two of them will quickly realize they have another important point of connection—though not one anyone would expect at first.

Sleepy Hollow Season 4 is slated to premiere in early 2017.

Gavankar, who played Luna Garza on True Blood and most recently starred as Meredith Bose in The Mysteries of Laura, is repped by APA, Sanders Armstrong Caserta Management and Felker Toczek.
