The fifth season of Arrow has introduced one of the most fearsome villains of the DC Comics Universe, Talia al Ghul (Lexa Doig), to the Arrowverse. Oliver Queen's struggle with Ra's al Ghul and his family and legacy has been well documented, but what wasn't known until recently is that the daughter of the demon helped train Oliver to become the Arrow.
However, executive producer Mark Guggenheim says that Oliver's former mentor isn't done with him yet. "We will see her in the present day," Guggenheim teased to Entertainment Weekly. "What she wants from Oliver in the past is very different from what she wants from him in the present."
For the time being, Oliver is unaware of Talia's distinguished lineage because Oliver never learned Talia's last name. "Oliver couldn't have heard it, because if he had, when Ra's talked about his daughter he'd be like, 'Yeah, the other daughter, I met her back in Russia,'" Guggenheim says. "We were very cognizant not to retcon anything. So yes, she is Talia al Ghul, but Oliver obviously doesn't know that."
Something tells us that Oliver's blissful ignorance may come to an end, and soon.
In the next episode of Arrow, titled "Checkmate," Oliver (Stephen Amell) gets closer to the truth about Prometheus. Meanwhile, Helix refuses to continue helping Felicity (Emily Bett Rickards) until she does a favor for them.
Arrow airs Wednesdays at 8 p.m. ET on The CW.
After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea. Oliver returned home to Star City, bent on righting the wrongs of his family and fighting injustice. As the Green Arrow, he protects his city with the help of former soldier John Diggle (David Ramsey), computer science expert Felicity Smoak (Emily Bett Rickards), his vigilante-trained sister Thea Queen (Willa Holland), former police captain Quentin Lance (Paul Blackthorne) and brilliant inventor Curtis Holt (Echo Kellum).
Newly appointed Mayor Oliver Queen finds himself challenged as he fights on two fronts for the future of Star City. With Diggle back in the military and Thea adamant about hanging up her hood as Speedy, Team Green Arrow is down to just Oliver and Felicity – but they're no longer the only vigilantes in town. Green Arrow's public defeat of Damien Darhk at the end of Season Four has inspired a new crop of masked heroes to step up and defend the city, though their painful inexperience makes them obstacles, rather than allies, in the field. The arrival of a deadly new adversary will force Oliver to confront questions about his own legacy, both as mayor and as the Green Arrow.
