WARNING: The following contains spoilers for Star Wars: The Rise of Skywalker, in theaters now.
FN-2187 was just another grunt in the First Order when he first encountered Poe Dameron, a pilot for the Resistance. Escaping alongside his new comrade, the newly dubbed Finn became a valued ally to Poe, a dedicated friend to Rey and one of the leaders of the Resistance. But while he's spent most of the series appearing to just be a regular man, that might not be the case.
There are multiple hints throughout The Rise of Skywalker that Finn (John Boyega) may actually be Force-sensitive, suggesting he could even eventually learn to be a Jedi.
A FEELING
It turns out that Finn has actually been considering his place in the universe since breaking off from the First Order, contemplating about the Force. Finn offers a surprisingly philosophical idea of what the Force is. While explaining his own belief in it to Jannah, Finn says he believes that the Force is the part of him that kept him from becoming another killer like any of the other Stormtroopers. When Jannah explains how she had a similar experience when her entire squadron refused to fire on civilians, he describes it as the Force moving through them: a feeling that something is wrong, and knowing to listen to it.
Finn has a couple of these feelings throughout the film, at one point even saving the entire Resistance by being able to adjust their plans. While approaching the Final Order's fleet of Star Destroyers, the Resistance locates a communications tower. This is what's giving the ships their orders until they get out of the atmosphere. If they can destroy the tower, the Star Destroyers won't be able to move for a small window of time, allowing the Resistance the one and only chance to bring them down. But the Final Order is able to redirect the signal to the command ship, leaving the Resistance with no spot to target. Finn is able to feel out where the signal has been moved too though by using the Force, allowing the Resistance landers to target the Star Destroyer instead. This keeps the plan on track and helps ensure that it can succeed.
A CONNECTION
The films have always shown the Force as creating links between people. People who love each other are often able to reach out across the galaxy to feel each one another and speak to them. While Finn doesn't exhibit any full control over this like Rey seems to possess with Kylo after a point, it does seem to exist within him. He can actually feel it when Rey collapses after her battle with the Emperor and screams out in horror when it appears that she's died.
All of this suggests that Finn is at least Force Sensitive. While he doesn't have the implicit power that Rey possesses, it could allow him to actually train and learn from her. If he continued to develop his powers, that could prove to be an exciting direction for Finn to take in a post-war galaxy. He could even become one of Rey's first students if she decides to continue to teach the lessons of the Jedi, helping her bring balance and peace to the galaxy. She had almost completed her training alongside Leia when she departed to stop Palpatine, which she could easily share with Finn. She's never going to find a more loyal person to make her padawan, and it would complete his journey from an insignificant Stormtrooper to one of the most important people in the entire galaxy.
