In a sneak peek video, executive producer Wendy Mericle teases an exploration of the differences between Oliver and Diggle. "We are going to explore the reasons why he and Diggle are still at odds. Basically goes back to what happened at the end of season 3 When Oliver made the decision to try to take down the League of Assassins from the inside and wound up kidnapping Lyla and endangering baby Sara," she says.
Meanwhile, cast member Barrowman teased about the resurrection of Sara and Tommy. "I know that Malcolm is greatly affected and hurt by what happened to Tommy. But when you watch tonight, you'll see where Malcolm stands on the fact of this resurrection thing, because it's not like it's a spa where he's like, 'hey, come on in, let me resurrect you!' He wanted control of that for himself," he told Variety.
"Arrow" airs on The CW every Wednesday at 8pm.
