Spoilers ahead for Thursday's DC's Legends of Tomorrow.
In Thursday night's DC's Legends of Tomorrow on the CW, young actress Milli Wilkinson made a surprise debut as Talia al Ghul. The former Twilight and Once Upon a Time actress plays the elder daughter of Ra's al Ghul, who has been a major part of the CW-verse along his other daughter, Nyssa al Ghul.
In "Left Behind," Talia debuted when Sarah Lance (played by Caity Lotz) visited Nanda Parbat while stuck in the 1950s. Sara offers to train the young Talia, who appears to be a pre-teen.
The CW nor the show's producers have revealed if and when Wilkinson will appear again as Talia al Ghul.
DC's Legends of Tomorrow airs Thursdays on the CW.
