"I had an overall arc that in mind that [JJ Abrams] wanted to do," Driver continued. "His idea was that [Kylo's] journey was the opposite journey of Vader, where Vader starts the most confident and the most committed to the dark side. And then by the last movie, he's the most vulnerable and weak. He wanted to start with the opposite. This character was the most confused and vulnerable, and by the end of the three movies, he would be the most committed to the dark side. I tried to keep that arc in mind, regardless if that wound up not being the journey anyway, because it changed while shooting. But I was still focused on that."
Driver said Rian Johnson took Kylo Ren's original arc in "a different direction" with "The Last Jedi," although "it still tracked with the character." That wasn't the case with "The Rise of Skywalker."
"The last one, it changed into being, you know, about them and the dyad, and things like that," Driver said. "And evolving into Ben Solo. That was never a part of it. He was Ben Solo from the beginning, but there was never a version where we'd see Ben Solo when I first signed up for it."
