Arrow Season 5 is starting to look a whole lot like Season 2. Just one day after Manu Bennett’s Deathstroke was announced to return for some finale “desperate measures,” so too is Season 2 addition Katrina Law making Nyssa al Ghul’s Season 5 debut for a showdown with her comic half-sister, Talia.

Per Entertainment Weekly, the former Spartacus and current Training Day star will return 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 first debuted in Season 2 as a League of Assassins emissary and Sara’s ex-love, though the more recognizable Talia didn’t make her Arrow-verse debut until Season 5 (barring a young Legends appearance).

Back in January, executive producer Marc Guggenheim teased “They’re close enough and different enough that I would love, at some point, to do a story with Nyssa and Talia.” Arrow Season 5 also had to sidestep the question of Oliver first meeting Talia in flashback, but not knowing of her al Ghul heritage before meeting Nyssa in Season 2, or Ra’s in Season 3.

In the meantime, Arrow Season 5 will kick off its final episodes on April 26 with “Dangerous Liaisons,” the trailer for which you can see below. And hey, while we’re at it, don’t forget about the other Ra’s al Ghul headed to Gotham!
