"Arrow's" fifth season has seen an influx of new blood arrive in Oliver Queen's Arrowcave, just as Oliver Queen himself got elected to mayor of Star City. Those two plot lines will converge in the next new episode of the CW superhero series, an installment titled "Spectre of the Gun."

The episode, which saw a promo debut earlier this week, will focus on gun control in Star City -- surely a hot topic considering all the vigilantes and criminals running loose in the city. Additionally, the episode will dive into the backstory of one of those new vigilantes, Wild Dog. New photos released for the episode by the CW show Wild Dog in action as Rene Ramirez and Oliver Queen coming under attack.

WILD DOG'S HISTORY IS REVEALED -- A traumatic attack on City Hall triggers painful memories for Rene (Rick Gonzalez) about his family. Flashbacks reveal how Rene went from simple family man to a hero named Wild Dog. Meanwhile, Oliver (Stephen Amell) must deal with the perpetrator behind the attack and realizes the best way to do so is as Mayor Queen instead of the Green Arrow. Tensions run high in the Arrow bunker. Kristin Windell directed the episode written by Marc Guggenheim (#513).
