An extended trailer has arrived for the Season Five finale of Arrow, "Lian Yu," which promises an uneasy alliance between Oliver Queen and former foes Slade Wilson, Malcolm Merlyn, Nyssa al Ghul and Digger Harkness.
In the previous episode, "Missing," Adrian Chase escaped A.R.G.U.S. custody and captured most of Team Arrow's members. With deadly opponents such as Talia al Ghul (Lexa Doig) and Black Canary (Katie Cassidy) at Chase's side, Oliver must turn to old enemies to save his friends.
In addition to the members of Team Arrow, Chase is using Oliver's son William as leverage. "If you want to get your son back, you know what to do," says Chase, who's trying to reinforce the idea that Oliver enjoys killing. "I have no interest in this being a fair fight," Oliver responds.
Airing Wednesdays at 8 p.m. ET/PT on The CW, Arrow stars Stephen Amell as Oliver Queen, Emily Bett Rickards as Felicity Smoak, David Ramsey as John Diggle, John Barrowman as Malcolm Merlyn, Willa Holland as Thea Queen, Paul Blackthorne as Quentin Lance, Echo Kellum as Curtis Holt and Josh Segarra as Adrian Chase.
