In related news, Laurel Lance's (Katie Cassidy) transformation into the Black Canary has been one of the focal points of Season 3 of Arrow, but she is still without the Canary Cry, a key feature of the character from the comics. But could the change on an upcoming episode of The Flash?

Some new photos from the episode "Who Is Harrison Wells?" seem to indicate that Cisco (Carlos Valdes) supplies Laurel with a device to use the Canary Cry.

Comic Book Movie has the photos, which you can check out here.
