The actor has been teasing bits about Oliver's fate in this chapter and some of the information alludes to Oliver's moving over to the League of Assasins and joining the antagonistic force.

During a recent fan interaction via Twitter he responded to a fan asking him what his favorite part about season 3 was, revealing he might be getting ready to play dark Oliver.

"Evil Oliver. Coming soon," he tweeted in reponse.

On April 17, Amell also tweeted stating that his character will be in combat mode in the finale.

"It's our last day of Season 3. Like the last day of Season 1 and Season 2... I'm going out fighting," Amell tweeted.

It has been strongly rumored that Oliver will be turning over to the dark side and taking Ra's al Ghul (Matt Nable) on his offer to join the League of Assassins. The synopsis for the next episode of season 3 states that Oliver will "go through a rigorous transformation." Could this be to make the transition to the dark side?

The next episode, titled 'Al Sah-him' will air on April 22 on The CW.
