In various comic book versions, the two had a mother-daughter relationship and both suited up as the Black Canary and working to save the people of their city.
Meanwhile, as promised by the showrunners the backstory of Oliver Queen on “Arrow” will finally end in the current fifth season so there will be none of it in its sixth season.
Talia Al Ghul is likely to have an influence on Oliver as she was the one who trained the old vigilante. It was revealed that she wanted to push Oliver to go back in his city and fight what he has left behind and finished what he started.
All along it was his father’s mission to save the soul of his city and through that, Talia trained Oliver well to prepare him for crime-fighting deeds, which seem to be an emotional start and end for Oliver’s dark past as the Gree Arrow.
Arrow Season 5 Episode 12 titled “Bratva” would be airing next week and based on the synopsis, it will feature Team Arrow’s ride to Russia in their quest to finally unveil the true identity of Prometheus.
