A small little question was answered once and for all on Arrow Season 4 Episode 18.
And that question was this: WHO IS IN THE GRAVE?!?
Indeed, the latest installment of this CW favorite revealed the identity of the main character who we first learned died on the season premiere.
Elsewhere during the hour, Oliver and Diggle discovered Merlyn’s plan to break Darhk out of jail; while Laurel received a rather surprising offer.
Also, Felicity had an important talk with Curtis.
