Arrow Season 2 Spoilers: Katrina Law returns as Nyssa Al Ghul in finale

One of the strengths of the CW's Arrow is that it successfully weaves in characters from the broader DC universe, such as the Suicide Squad and Deathstroke. And it looks like another guest character will return for the upcoming Season 2 finale.

Green Arrow TV posted a screenshot of Katrina Law as Nyssa Al Ghul, who shows up in the final episode as part of the ongoing battle between Oliver and Slade.

"[Sara] went to go get help, because when you're fighting an army, you need an army," executive producer Andrew Kreisberg told the site. "She goes and gets Nyssa, and she comes back with the League. It's the Arrow, Canary, Roy and the League of Assassins vs. Slade and his Mirakuru army for the city."

That sounds like a pretty epic way to cap off the show's sophomore season. In related news, here is the official description for the finale:

"OLIVER MUST DECIDE ONCE AND FOR ALL IF HE'S A KILLER OR A HERO - Slade (Manu Bennett) moves forward with his plan to kill one more person in Oliver's (Stephen Amell) life. While Oliver has fought all year to be more than the killer he once was, when Slade kidnaps someone close to Oliver's heart, Oliver is pushed to the edge and realizes sometimes it takes doing the unthinkable to stop the monster. Meanwhile, Diggle (David Ramsey) takes on Amanda Waller (guest star Cynthia Addai-Robinson) with a little help from some friends, and Thea (Willa Holland) turns to Roy (Colton Haynes) in her time of need."
