Sleepy Hollow‘s Jenny Mills can’t let her guard down just yet, because the Fox series has made a series regular of Jessica Camacho.

Camacho debuted in the current season’s third episode, playing Sophie Foster, who (like Abbie’s sis) has experience obtaining artifacts and a connection (however murky) to the dearly departed Sheriff Corbin.

The Hollywood Reporter first reported the promotion.

Camacho’s TV credits include Longmire, Bones, Castle, Veronica Mars and Last Resort.
