New Extended Promo For ARROW Season 3 Episode 18: "Public Enemy"

DONNA SMOAK RETURNS - During an attack on the mayor's office, Ray (Brandon Routh) is critically injured. Felicity (Emily Bett Rickards) is pleasantly surprised when her mother, Donna Smoak (guest star Charlotte Ross), shows up at the hospital to offer her support. With the SCPD out in full force looking for the assailant, Oliver (Stephen Amell) and his team work hard to stay one step ahead of the police to find the man responsible. However, things come to a head when Ra's al Ghul (guest star Matt Nable) kidnaps Captain Lance (Paul Blackthorne). Dwight Little directed the episode written by Marc Guggenheim & Wendy Mericle (#318)./big>

Determined to right the wrongs of Starling City and sworn to bring justice to those who have failed it, Oliver Queen (aka The Arrow) — with the help of his iron-fisted right hand, John Diggle, the tech-savvy Felicity Smoak and the newest member of the team, Roy Harper — narrowly defeats the vengeful Slade Wilson, his onetime ally and mentor on the island of Lian Yu. But like all wars, there are casualties. Sacrificing herself for her children, Moira Queen falls at the hand of Deathstroke, sending Oliver’s sister, Thea, into self-imposed exile with her biological father, Malcolm Merlyn. In Season Three, Oliver faces an even greater threat, when another lethal face emerges from his dark and tortured past – Ra’s Al Ghul!
