The CW has released the first promo photos for episode 2.15 of "Arrow," which you can check out in the gallery viewer below. Titled "The Promise," the episode is described as follows:
"Oliver is shocked when he learns that Slade has come to Starling City. Back on the island, as Oliver, Slade and Sara prepare to take over the freighter from Ivo (guest star Dylan Neal), Sara pulls Oliver aside and tells him he needs to kill Ivo to prevent him from telling Slade what happened with Shado. Oliver feels immense guilt over the situation but realizes Slade’s growing rage from the Mirakuru makes him unpredictable and he could turn on his friends if he thinks Oliver is to blame. Oliver agrees to kill Ivo and the battle begins."
Directed by Glen Winter and written by Jake Coburn & Ben Sokolowski, "The Promise" is scheduled to air on March 5. "Arrow" airs on Wednesdays at 8 P.M. ET/PT on The CW.
