TV Everyone's in danger in explosive new Arrow trailer Footage teases showdowns, a return, and one major near-kiss... By Natalie Abrams Natalie Abrams Senior Writer EW's editorial guidelines Published on April 20, 2017 12:09PM EDT Photo: Bettina Strauss/The CW Arrow is about to heat up in a big way. As the CW super series charges full circle toward Oliver (Stephen Amell) escaping the island he once called home in flashbacks, the future Emerald Archer will be gearing up for his ultimate showdown with Prometheus (Josh Segarra). In a new trailer, posted by Amell on Facebook, everyone in Oliver’s life is in danger as a result. But that will make for one epic finale as the video also teases other big showdowns — like Nyssa (Katrina Law) vs. Talia al Ghul (Lexa Doig) and Black Siren (Katie Cassidy) vs. Black Canary (Juliana Harkavy) — the return of Slade Wilson (Manu Bennett), and a near-kiss between Oliver and Felicity (Emily Bett Rickards)?! Arrow returns Wednesday at 8 p.m. ET on The CW.
