Kirshner will appear in the recurring role of Isobel, the wife of history teacher Alaric (Matt Davis).

It was said that she will make her debut in the January 21 episode of the show, an episode which has already been shot. An insider to the site said that "11th-hour reshoots" will take place to fit Kirshner into the show in time.
