New International Promo For ARROW Season 3 Episode 17: "Suicidal Tendencies"

DIGGLE MARRIES LYLA; THE SUICIDE SQUAD RIDES AGAIN - It's celebration time as Diggle (David Ramsey) and Lyla (guest star Audrey Marie Anderson) get married. However, Deadshot (guest star Michael Rowe) interrupts their honeymoon and tells them the Suicide Squad has been given a new mission - rescue United States Senator Joseph Cray (guest star Steven Culp) from a hostage situation in the Republic of Kasnia. Amanda Waller (guest star Cynthia Addai-Robinson) breaks down the mission and introduces them to the newest member of the Suicide Squad, Cupid (guest star Amy Gumenick). Meanwhile, Oliver (Stephen Amell) learns about Ray's new Atom costume and the two have a heated stand-off. Felicity (Emily Bett Rickards) and Ray hit a rough patch. Jesse Warn directed the episode written by Keto Shimizu (#317).

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!
