Jes Macallan has joined DC's Legends of Tomorrow as Ava Sharpe, a special agent in a newly-instituted Time Bureau, according to Deadline. Macallan is scheduled to have a recurring role in the upcoming third season, in this apparently original-to-television part.
Macallan's Sharpe is the member of the Time Bureau, a new branch of the U.S. federal government led by Rip Hunter (Arthur Davill) that regulares time travel.
The character herself is described as "very smart and incredibly ambitious and always believes she is the smartest person in the room. She is often quite ruthless in obtaining her goals and her drive for perfection has left many discarded friendships (and relationships) in her wake."
Macallan is best known for playing Josslyn in ABC's Mistresses.
DC's Legends of Tomorrow is scheduled to return for its third season October 10 on the CW.
