Surprisingly, Talia is only appearing in flashbacks for now, aiding Oliver in his efforts to take down Kovar: TALIA AL GHUL TAKES OLIVER UNDER HER WING — In his quest to take down Kovar, Oliver (Stephen Amell) gets help from a surprising source – Talia al Ghul (guest star Lexa Doig).
It’s worth wondering how Oliver gets involved with Talia al Ghul, given that he didn’t seem to have much knowledge of the League of Assassins until Sara’s return in Season 2.
A new synopsis for February’s “Second Chances” sees Oliver teaming up with Bruce Wayne’s sometime love interest, albeit at a deadly cost.
The Arrow-verse technically introduced us to Ra’s al Ghul’s daughter Talia once before, but the famed Batman character’s visit to Oliver’s world has been a mystery until now.
