After a violent shipwreck, billionaire playboy Oliver Queen, was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea by two men on a fishing boat.

 * The penultimate episode will serve as a backdoor pilot to introduce a new female-led spin off, starring Katherine McNamara, Katie Cassidy and Juliana Harkavy.
 * Season 8 would've been the first since Season 2 to feature two episodes named after songs by Bruce Springsteen including the penultimate episode that's seen as a tradition in almost every season of Arrow. But according to Marc Guggenheim, the latter episode's original title "Livin' In the Future" was changed at the request of Warner Bros. due to the inclusion of the backdoor pilot for the proposed Green Arrow and The Canaries spin-off.
