The pictures already suggested that it could very well be the last time that the Green Arrow and Damien Darhk will face off in “Arrow.” And it certainly was the last.
Oliver eventually teamed up with a surprising force to stop Damien Darhk and his magic once and for all and save Star City from his wicked ways.
Incidentally, the mystery that Season 4 of “Arrow” showed in its premiere episode had been unraveled after the 18th episode.
Towards the end of the first episode of the fourth season of “Arrow,” Oliver Queen was shown half-sitting in front of a tombstone with Barry Allen, played by Grant Gustin, from “The Flash” TV series standing behind him and consoling him afterward.
The biggest question then was the identity of the person in the grave who seems to be quite close to Oliver that the latter was so distraught and even promising to take revenge for.
It has become clear that the person in the grave was no other than Dinah Laurel Lance or the Black Canary, played by Katie Cassidy, after she was killed by Damien Darhk in episode 18.
That surely left Oliver quite distraught especially coming on the heels of his separation with Felicity. Laurel, after all, was a former girlfriend while Felicity is still his wife.
