The CW has released the official synopsis and promo for Arrow season 3, episode 17 titled Suicidal Tendencies and it reveals that the Suicide Squad is back. Check it out below:

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).

Moreover, Oliver (Stephen Amell) learns about Ray's new Atom costume and the two have a heated stand-off and Felicity (Emily Bett Rickards) and Ray hit a rough patch.

Suicidal Tendencies will air on Wednesday, 18 March at 8pm ET on The CW.

Meanwhile, Stephen Amell was at Kansas City's Planet Comicon last week where he revealed that he pitched a crossover idea involving CW's Arrow and Supernatural. (via ComicBookMovie)

"I pitched an idea yesterday to the President of Warner Bros. TV Greg Berlanti, who runs Arrow, Flash, Supergirl, just did Pan - he's a genius - and Mark Pedowitz, who runs the CW," Amell said. "I pitched something called fan-fiction live. I pitched an idea where we would take Arrow and Supernatural and write a fan-fiction crossover episode and do a live-reading."
