During an appearance at Fan Expo Boston ( via Screen Rant ), Boyega, who played Stormtrooper turned Rebel soldier Finn in the “Star Wars” sequel trilogy, said he expected his character to become a Jedi alongside Rey after “The Force Awakens.” He also thought they were destined to become enemies after they both mastered the Force.

The Star Wars sequel trilogy could have taken a far more dramatic turn than what we got, at least in John Boyega ’s mind. The actor recently revealed that after reading the Star Wars: Episode VII – The Force Awakens script,

Anakin Skywalker, meanwhile, was trained by Obi-Wan in the hopes of bringing balance to the Force.

John Boyega shares initial expectations for Finn's role in the Star Wars sequel trilogy, including a potential Rey vs. Finn storyline that never materialized.
