Wild Dog's backstory will be revealed next week on "Arrow" in "Spectre of the Gun." In the new teaser for the episode, Mayor Queen is asked about his position of gun control, an issue he concedes is "complicated" -- made more so by the fact that Team Arrow uses firearms.

The episode will also address Wild Dog's thoughts on guns: He employs them often, but his reliance may stem from a tragedy from a past. We know Rene Ramirez was dishonorably discharged from the military, and that something that happened to his family inspired him to become a vigilante.
