There's an unresolved moment in Star Wars: The Rise of Skywalker where Finn, thinking he's about to die, tries to make a confession to Rey. The film never explains what he wanted to tell her - though it makes several light references as it goes on.
Co-screenwriter Chris Terrio has now addressed the scene after the fact - and though he's reticent to be definitive, he points to evidence in the film that suggests Finn's secret isn't what you may have thought.
"Well, you can read that how you want to. There are some people who read it as Finn having feelings for Rey; there are some who read it as Finn trying to make that Force-related confession," Terrio told The Hollywood Reporter. "What’s undeniable is that in the middle of the battle, when the source of the navigation signal is changed, Finn has a very strong sense of where it is, and that’s knowledge he couldn’t really have unless he was using the Force."
"Hopefully, the film also suggests that Finn is discovering that he is a Force user and is Force strong. Finn feels the death of Rey, and in a crucial moment during the battle, Finn senses the command ship where the navigation signal was coming from," Terrio continued. "So, we wanted to begin to plant the idea that Finn is Force strong and that there are other people in the galaxy who are Force strong."
However Terrio also stated that "family" was a core Star Wars theme that had to be addressed in the latest trilogy's conclusion. And for Rey, the filmmakers felt this meant exploring both her birth family - the Palpatines - and her chosen family - the Skywalkers.
"Yes, of course, the galaxy is full of Force users, and you don’t have to be a Skywalker or a Palpatine in order to be strong with the Force. But Luke does say very explicitly in Return of the Jedi, 'The Force is strong in my family,' and we know that there is an inherited element to Force power," Terrio explained. "So, considering that this was a story of the Palpatines and Skywalkers, at least these nine movies, we decided to focus on the family part.
"We couldn’t agree more with the debate about the democratization of the Force, but for purposes of this story, we thought that it was a more interesting and mythic answer if it turned out that Rey descended from one of the families that has been at the center of this whole saga the entire time. In the end, the film asserts that there are things stronger than blood because she chooses a different family for herself."
