User blog:Captian Griggs/Andy Diggle alive?

In the latest Arrow episode "Restoration" Green Arrow and John Diggle were chasing after two H.I.V.E. agents, one of had a gun pointed at John for a few moments but instead of kill him he fled instead. If you look closely between the mask and the glasses it looks like the H.I.V.E. agent in question is an African-American, could the agent in question be Andy Diggle? If so I don't know why he'd be working for H.I.V.E. but it'd be a good twists to have John's brother working for the bad guys.
