As a part of TV Guide‘s “Mega Buzz” spoilers article, the site shares some small pieces of information surrounding Arrow‘s take on Nyssa al Ghul (Katrina Law). The daughter of Ra’s al Ghul will make her debut on the series in Episode 13, “Heir to the Demon”. According to TV Guide, this take on Nyssa, who is visiting Starling City to find Sara Lance/Black Canary (Caity Lotz), will be similar to sister Talia. No further details are given.
The site also adds another interesting tidbit. Law was previously up for the role of Shado, and nearly landed the part. However, since she would be sharing a number of scenes with Manu Bennett’s Slade Wilson, the Arrow creative team “thought it would be Spartacus overkill.” Of course, Celina Jade ended up being cast as Shado. Arrow returns to The CW on January 15th.
