ABC's fairy tale drama has officially cast Teen Wolf actor Sinqua Walls in the role of Sir Lancelot for the new season, The Hollywood Reporter confirms. He has been booked for one episode.

Sir Lancelot will be introduced as a one-time member of King Arthur's Round Table who has been expelled, as TVLine first reported.

Walls' casting comes as the hourlong series previously booked Jamie Chung as Mulan and Sarah Bolger as Sleeping Beauty.

It was revealed at Comic-Con earlier this month that characters like Captain Hook and Jack and the Beanstalk would also be introduced in the new season.

Repped by Innovative Artists, Walls has appeared in The Secret Life of the American Teenager, Friday Night Lights and Californication.

Once Upon a Time returns this fall on 8 p.m. Sundays.
