Arrow, the show that spawned The CW’s sprawling DC shared universe, is now in its fifth season and closing in on its 100th episode. Oliver Queen a.k.a. The Hood a.k.a. The Arrow a.k.a. The Green Arrow has been through a lot of adventures across those episodes, both in the president day and in the series’ ongoing flashbacks, and some of his most notable adventures have involved the al Ghul family.

Already Arrow fans have gotten to know Ra’s al Ghul (Matt Nable) and Nyssa al Ghul (Katrina Law) very well, but now another member of the infamous family set to join Arrow in season 5. CBR reports that Lexa Doig (Continuum) is set to play Talia al Ghul, Nyssa’s half-sister. Doig has landed a recurring role in Arrow, and will make her first appearance in season 5, episode 10, “Who Are You?” According to The CW’s official description of her character, Talia is “an elite warrior who doesn’t pick sides but rather creates her own.”

Talia al Ghul has already appeared in the Arrowverse, though not in Arrow; a season 1 episode of Legends of Tomorrow, “Left Behind,” featured Talia as a child (played by Milli Wilkinson), and also saw Nable reprise his role as Ra’s al Ghul. The most famous on-screen portrayal of Talia al Ghul was in Christopher Nolan’s The Dark Knight Rises, where the character was portrayed by Marion Cotillard.
