John Barrowman will be a Change Agent!.. “The thing about John's character is, he’s a character in the form of an inciting incident, or [rather] an inciting incident in the form of a character — he’s like a stone thrown in the pond. You see him injected into the story and there’s ripple effects throughout the entire series and each ripple is a different character on the show.
He further added that “When he interacts with one character it creates this different dynamic, when he interacts with another character it creates a completely different dynamic, so he’s like a change agent for the series.”
So just who will John play? Will he be Oliver's side or be the force against him?
