What did Arrow star Stephen Amell know, and when did he know it?

Speaking with TVLine at the CW Upfronts the morning after the superhero hit served up its Season 3 finale, Amell revealed just how (very!) long he has known that Oliver and Felicity would — literally — ride off into the sunset together. But as he notes in the video Q&A above, the Arrowverse is (sigh) seldom kind to the happy.

Amell also shares what all he knows about Season 4, including the biggest question at hand: If Oliver can’t be the Arrow again, what now? Also, will a certain namechecked baddie Darkhen the show’s doorstep again? Press play for those answers and more.
