As the scenes move along, a nervous Diggle is seen down on his knees in front of Oliver, and Ra's al Ghul's voice plays in the backdrop, stating, "you must eliminate him."

In a recent interview with TVLine, showrunner Marc Guggenheim spoke about what fans can expect from the upcoming episodes after Oliver's move to the dark side.

Guggenheim revealed that this would be a very tough time for team Arrow in Starling City to know that Oliver is playing for the anatgonistic side now.

"The character journey of [Episode] 321 is how the hell Team Arrow moves forward without Oliver," Guggenheim said. He also added that "knowing that he's out there and alive, but a member of the League of Assassins, that's a whole lot harder."

'This is Your Sword' will air on The CW on April 29.
