Arrow: City of Blood Easter Eggs and DC Comics References

This week’s episode of Arrow went widescreen with the stakes, but fairly intimate with the actual action relative to what we’ve seen recently.As such, many of the Easter eggs this week are really just retreads of existing stuff (not unlike what last night’s episode of Marvel’s Agents of S.H.I.E.L.D. did).We’ll run down the characters who reappear after an absence, though, and the handful of other little things we spotted.
