Arrow: Katrina Law returns for epic Nyssa vs. Talia al Ghul showdown

Arrow type TV Show network The CW genre Superhero

Another familiar face is returning to Arrow.

EW has learned exclusively that Katrina Law will reprise her role as Nyssa al Ghul for multiple episodes that culminate in an epic fight between Nyssa and her half-sister Talia al Ghul (Lexa Doig) in the upcoming season 5 finale.

Law, who currently stars on CBS’ Training Day, first appeared in season 2, where viewers discovered that when Sara (Caity Lotz) left the island, she joined the League of Assassins and struck up a romance with Nyssa, the youngest daughter of Ra’s al Ghul (Matt Nable).

Talia, meanwhile, didn’t appear until season 5, when it was revealed that she helped train Oliver (Stephen Amell) in Russia — but she also trained his foe Prometheus (Josh Segarra) after learning that Ollie killed her father. Talia had long ago left the League to create her own cult of warriors after she realized her father would never allow her to be the Head of the Demon.

Ever since Talia’s introduction, the eventuality of an epic showdown between the pair has been highly anticipated. “They’re close enough and different enough that I would love, at some point, to do a story with Nyssa and Talia,” executive producer Marc Guggenheim previously told EW.

The news comes on the heels of Amell revealing that Manu Bennett will also be reprising his role as Slade Wilson, a.k.a. Deathstroke, for the season ender.

Arrow airs Wednesdays at 8 p.m. ET on The CW.
