In an unusual twist for Arrow, the previous season didn’t dispatch with its main villain.
All in all, Diaz only appeared in 13 of the sixth season’s 23 episodes.
While that’s still a healthy number of episodes, Kirk Acevedo’s bump up to regular status could mean that he appears in even more in the seventh season.
Oliver typically takes out his supervillain of the year by the final minutes of each finale, but Diaz was free and Oliver was off to prison when the closing credits rolled last spring.
