Many mysteries dominate the new Star Wars trilogy, the mystery of Supreme Leader Snoke, what Luke Skywalker is doing in Ahch-To, the identity of Rey's parents But what about Kylo Ren?
The Knight formerly known as Ben Solo has a mysterious past that has been mocked in movies, and even Adam Driver does not know all the details. He talked about the fun of playing a mysterious character with Screen Rant.
"I mean, it's like a bit of pieces that we started working on that kind of thing," Driver said, "I know it's answered in this one that we started in The Force Awakens that I knew he was operating, you know when we were doing that, he knew that as time went on they revealed themselves, but even if those things, there are a lot of those things that will never be revealed and there are no plans. "
So, although some fans may be disappointed that every aspect of Kylo Ren's story does not unfold on the screen, that's normal in a Star Wars movie.
Before the prequel movies, the story of Anakin in the Jedi Order and the rise to power of Emperor Palpatine were two mysteries. So, sure, future movies (or books, comics, etc.) could end up exploring more of Kylo Ren's background story, but those details are not important to the current story.
"There are things I think about that, for me, it's what makes it more fun to play with, you know," said Driver.
Every actor needs some kind of creative freedom to fully realize their characters and give them life. Even Mark Hamill, who did not know all the details about Luke Skywalker's time between The Return of the Jedi and The Force Awakens invented his own story to return to the character.  So, although some aspects of Kylo Ren's character and background story might remain shrouded in mystery, the relevant details that are important to the story will eventually come to light.
We will learn more about the executor of the First Order when Star Wars: The Last Jedi opens in theaters on December 15.
