One of the Time Bureau agents we will see throughout the season is Jes Macallan (Mistresses). Macallan will be playing Special Agent Ava Sharpe who is described as a hard-working agent for the Time Bureau. <P><P> Ava is a very smart and extremely ambitious woman who always thinks she is the smartest person in the room. She is also described as quite ruthless when trying to obtain her goals and her hunger for perfection has cost her some friendships and relationships.
