Oliver Queen (Stephen Amell) must contend with a dangerous gun runner dubbed The Mayor in next week's episode of Arrow entitled "Crucible". The CW Network has released a promo for this episode, which shows Oliver squaring off with the mysterious Black Canary (Caity Lotz) while trying to stop The Mayor (Clé Bennett), who is flooding Starling City with illegal firearms. Check out what else is in store for Arrow fans as Season 2 continues.
Oliver (Stephen Amell) discovers a man who goes by the name "The Mayor" (guest star Clé Bennett) is bringing illegal guns in to The Glades, so Oliver sponsors a "Cash for Guns" event to help clean up the city. Unfortunately, The Mayor crashes the event with his gang and seriously injures Sin (guest star Bex Taylor-Klaus). The Canary (Caity Lotz) is furious when she learns her friend is in the hospital and sets out for revenge. Meanwhile, Felicity (Emily Bett Rickards) stuns Oliver with a bit of information about the Canary, Donner (guest star Dylan Bruce) asks Laurel (Katie Cassidy) to dinner, and Diggle (David Ramsey) reconnects with an old friend.
