While Oliver Queen is presumed dead (he’s actually going through a rigorous transformation) on Arrow, his younger sister Thea is left all alone in the loft. Thea “often thinks with her heart not her head which often puts her in dangerous situations.”
Thea is portrayed by Willa Holland. She’s best known for her roles as Agnes Andrews on Gossip Girl and Kaitlin Cooper on The O.C. Story goes that Hollywood filmmaker Steven Spielberg was the one who encouraged Thea’s ex-stepfather Brian De Palma (Carrie, Scarface, Dressed To Kill), to get Thea into the business. She started modeling (with the legendary Ford Modeling Agency) at the age of 7. Arrow airs Wednesdays at 8pm on CW.
