Arrow Season 2 finale official description released

The official description for the Season 2 finale of the CW's Arrow has been released, and it pulls back the curtain on the final phase of Slade Wilson's, aka Deathstroke's (Manu Bennett), plan. It also could tease the return of the Suicide Squad.

"OLIVER MUST DECIDE ONCE AND FOR ALL IF HE'S A KILLER OR A HERO - Slade (Manu Bennett) moves forward with his plan to kill one more person in Oliver's (Stephen Amell) life. While Oliver has fought all year to be more than the killer he once was, when Slade kidnaps someone close to Oliver's heart, Oliver is pushed to the edge and realizes sometimes it takes doing the unthinkable to stop the monster. Meanwhile, Diggle (David Ramsey) takes on Amanda Waller (guest star Cynthia Addai-Robinson) with a little help from some friends, and Thea (Willa Holland) turns to Roy (Colton Haynes) in her time of need."

TVLine has posted some spoilers about the finale from executive producer Andrew Kreisberg:

"Titled 'Unthinkable,' the sizable season ender required Arrow to return to The Watchmen's sprawling cityscape set -- it's that big. 'There may have been a lot of what seemed like detours this season, but it all plays out in the last few episodes,' Kreisberg attests. 'Hopefully, everyone will see the method to our madness and find the finale to be an exciting culmination of the season, as opposed to just a great episode.'"
