Don’t peek behind the mask if you don’t want to know any more. But of course you do and you will.

You Can't Keep a Bad Criminal Organization Down

Diggle and Andy's acquaintance from the past was connected to Shadowspire. You know an organization is bad news when A.R.G.U.S. seems concerned. The group first appeared in the comics in DEATHSTROKE #53. They committed the usual terrible deeds: they supplied South American drug cartels, infiltrated governments, and tried to wipe out Washington D.C. with a weaponized plague. Shadowspire's ultimate goal was to embroil the world in chaos and anarchy—beginning with the United States—so they could step in to take control and profit from the chaos.

Lieutenant Joyner's name was inspired by the writer who created Shadowspire, Tom Joyner.
 

A Literary Name

Felicity picks up a cool new moniker in this episode—Overwatch. Don’t look for it within the DC Universe, though. You won’t find it. So why does that name seem familiar? It’s because Felicity shares her new ID with the title of Arrow executive producer Marc Guggenheim's debut novel, a spy tale that also features a shadowy organization intent on disrupting the world and a brilliant computer hacker.

See you next week!
