Katrina Law Cast As The Daughter Of Ra's al Ghul On 'Arrow'
Reported by Outsiders - 2013.11.19
Ra's al Ghul's daughter is coming to Starling City and is starting to ruffle some feathers. The character of Nyssa al Ghul, Ra's al Ghul's other progeny has been cast by Katrina Law and is a powerful member of the League of Assassins who's in pursuit of The Canary.
In the comics, Nyssa was the half-sister of Talia al Ghul, who is the character we saw in Dark Knight Rises played by Marion Cotillard. With Nyssa coming to town, it may give some credence to a popular theory that Isabel Rochev (Summer Glau) is secretly Talia.
