Speedy on Arrow

Arrow is bringing back a lot of familiar faces for its eighth and final season, including Oliver Queen's younger half-sister Thea who has since become her own crime-fighting superhero.

The CW has released the official plot synopsis for the final season's third episode, titled "Leap of Faith," that has the reunited Queen siblings investigating a maze of catacombs while John Diggle teams with Lyla on a separate mission. The episode itself will be directed by longtime Arrow cast member Katie Cassidy.

Willa Holland's return as Thea had been confirmed earlier this month with the release of official stills from the upcoming episode, showing Thea standing alongside Oliver and Talia al Ghul in an ancient tomb. Holland had starred as Thea ever since the first season, eventually leaving the main cast to return in the occasional guest-starring appearance.

In the previously released photos, Thea was seen sporting a new facial scar as the ensemble were joined by the League of Assassins. Given that her biological father Malcolm Merlyn had once held the role of Ra's al Ghul for a time, it is unclear how her relationship with Talia has progressed into Season 8.
