Killer or Hero: Arrow Season Finale “Unthinkable” Images & Scoop

Arrow’s breakneck pace seems to show no signs of stopping as the show heads into its season 2 finale on May 14.

Entitled “Unthinkable” the finale episode will see Ollie (Stephen Amell) facing a decision as to whether he really is a hero or just a killer when Slade (Manu Bennett) moves forward with his plan to kill another person in his life.

But when Slade kidnaps someone close to Oliver’s heart (tell us your best guess!), 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.

John Behringdirected the episode with story by Greg Berlanti and teleplay by Marc Guggenheim & Andrew Kreisberg.
