A few months back, we first learned that Katrina Law was going to appear on Arrow. She would be playing the role of Nyssa al Ghul, the half-sister to Talia al Ghul, also known as Nyssa Raatko.
Now thanks to IGN we have a look at Law as Nyssa and we know when she will be appearing. Nyssa will be in next week’s episode, “Heir to the Demon” and is looking to bring Sara Lance (Caity Lotz), aka Canary, back into the League of Assassins. Look for this episode of Arrow on February 5th at 8pm EST on The CW. (Source: IGN)
