'Arrow' Season 4: Nyssa Al Ghul Returns To Make Oliver Queen [SPOILERS]

The CW series Arrow definitely has a lot of memorable characters, but one of the most frequent returnees is the lethal Nyssa al Ghul. The character played by Katrina Law has provided some of the most jaw-dropping twists in the show, from the revelation that Sara Lance (Caity Lotz) is her lover to the forced marriage to Oliver Queen (Stephen Amell). Now it looks like Nyssa is coming back to Season 4 with an offer Oliver simply cannot refuse!

Comic Book Resources has just revealed the synopsis for Arrow Season 4 Episode 13, which is titled Sins of the Father. The synopsis confirms that Thea Queen (Willa Holland) is still struggling with the blood lust so her father Malcolm Merlyn (John Barrowman) steps in to help.

It is also confirmed that Law will return to reprise her role as Nyssa and that she will be having "a heart to heart talk" with Sara's sister Laurel Lance (Katie Cassidy). But more importantly, Nyssa has something huge lined up for Oliver.

But what is this mysterious offer from Nyssa? Will she be able to help restore Felicity Smoak (Emily Bett Rickards) from being permanently paralyzed? Or has she found a way for him to be elected mayor of Star City? There is a possibility that Nyssa may have figured out a way to defeat Damien Darhk (Neal McDonough) for good.

Nyssa's first appearance in Arrow was in the Season 2 episode Heir to the Demon, where she tries to make Sara return to Nanda Parbat. The character has appeared in the show numerous times since then, mostly to train Laurel so she can be as strong as Sara and to help Oliver defeat a powerful enemy. Here's hoping that Nyssa has returned to once again save the day.

The Arrow episode Sins of the Father will air on The CW on February 10.
