Arrow: Extended Trailer For Corto Maltese Released

The CW have released an extended preview for next week's episode of Arrow, titled "Corto Maltese."

The trailer is titled simply "Thea," perhaps a nod to tonight's simple episode title, "Sara."

The episode sees Oliver head off to find his sister, only to end up fighting off Merlyn's forces. And the question of whether or not to reveal to her that he's the Arrow appears to drive much of the episode's story.

Oliver (Stephen Amell) decides it's time for Thea (Willa Holland) to come back to Starling City, so he packs for Corto Maltese, where Felicity (Emily Bett Rickards) has traced Thea's whereabouts. Lyla (guest star Audrey Marie Anderson) asks Diggle (David Ramsey) to go with Oliver because one of her field operatives, Mark Shaw (guest star David Cubitt), has gone dark in Corto Maltese and she'd like him to look into it. Feeling responsible for Thea's departure, Roy (Colton Haynes) joins Oliver and Diggle on their journey. Shaw double-crosses Diggle, putting numerous A.R.G.U.S. agents, including Lyla, at risk. Meanwhile, Laurel (Katie Cassidy) meets Ted Grant (J.R. Ramirez), and Felicity adjusts to her new job.

The "Corto Maltese" episode of Arrow was directed by Stephen Surjik and written by Erik Oleson & Beth Schwartz. The "Corto Maltese" episode of Arrow airs on Wednesday, October 22, 2014 at 8 PM ET.
