'Arrow' Season 2, episode 21 video: Watch the 'City of Blood' extended promo
The "Arrow" Season 2 episode, "City of Blood," is likely to be a somber and dark installment of the series. Oliver and Thea have just lost their mother, Moira Queen, to the revenge plans of Slade Wilson. And it's not like the one-eyed villain plans to stop there.
But is there anything that Oliver can do to stop his enemy from raining down chaos on Starling City? A video promo for "City of Blood" makes it look like the path to victory is both dangerous and deadly.
Where is Oliver when Diggle asks (presumably) Amanda Waller to help find him? Who does Oliver tell that he's the Arrow? Is it Laurel? How will anyone stand up to Slade's mirakuru army of criminals?
Fans will find out when "City of Blood" airs Wednesday, April 30 at 8 p.m. ET/PT on The CW.
