The latest trailer for Season 2 of Arrow asks the question 'Who is Oliver Queen?' Is Stephen Amell's character the hero Starling City truly needs? Or a vicious killer who needs to be stopped? We also see footage with Summer Glau as Isabel Rochev. In addition, The CW has released the plot rundown for the fourth episode of Season 2, "Crucible", airing Wednesday, October 30 at 8 PM ET.
"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."
