Jes Macallan spent four years on the series Mistresses dealing with backstabbing and drama queens — so she should have no problem with the crew of the Waverider. Macallan has been signed on as the recurring role of Special Agent Ava Sharpe for the third season of DC's Legends of Tomorrow.
Ava is described as incredibly ambitious and ruthless, willing to sever ties — both platonic and romantic — when it suits her interests. She is part of a secret government bureau tasked with protecting history and regulating time travel.
The odds are the bureau in question is Rip Hunter's (Arthur Darvill) Time Bureau, which is interesting that it's being called a government agency. This means Ava will be an adversary of the Legends at times, but she could also be an ally if circumstances dictate.
Macallan is another new face for the series that has already announced that Billy Zane will be playing P.T. Barnum for an episode and Tala Ashe will be playing Muslim hacktivist Zari Adrianna Tomaz (the comic book Isis). We also learned at Comic-Con last week that Neal McDonough and Wentworth Miller would be be returning as different versions of Damien Darhk and Leonard Snart/Captain Cold, respectively.
DC's Legends of Tomorrow returns October 10th at 9 p.m. ET on the CW.
