One of the highlights of The Force Awakens was the introduction of Finn (John Boyega), a stormtrooper who defects to join the Resistance. Along the way he has a sort of epic bromance with rebel fighter pilot Poe Dameron (Oscar Isaac), making sexuality just one subject of many in the subsequent myriad theories about Finn. As The Last Jedi releases, the Internet is abuzz with new Star Wars fan theories, which of course means more speculation about FN-2187, AKA Finn.
Finn's role in both The Force Awakens and Episode VIII showcases him as an important part of the Star Wars universe, and there is plenty to already know when watching the latest Star Wars films. The mystery around Finn opens up all sorts of possibilities for who he is, where he came from, and what he is meant to do.
Here are a number of theories about Finn from Star Wars that will have you laughing, crying, grinning, and grimacing - perhaps all at once. There are potential SPOILERS for The Last Jedi, if anyone happens to be correct in their hypothesizing.
KenDefender has a fun theory about Han Solo that seems like something Han would actually do, that rascal:
"I was just thinking about The Force Awakens and the whole "we'll have to go through this shield at lightspeed" thing and how stupid it was, then I remembered something I'd heard about hyperspeed in SW: that a planet's gravity will pull an object out of hyperspace. Since this is the case, entering the planet's atmosphere would automatically pull the Millennium Falcon out of warp.
Instead of just telling Finn this, and that all he would have to do is shut off the conventional thrusters, Han let Finn believe that he had literal 'faster than light' reflexes, an impossible feat."
Wilwander believes that Finn has some connection to the Force (even if it pales in comparison to the likes of Rey) and makes a well reasoned argument to support the theory:
"*Finn is seemingly the only stormtrooper to have broken his conditioning, backed up by the incredulous reaction by Ren when talking to Hux about it.
*This happens shortly before the conversation between Snoke and Ren 'There has been an awakening. Have you felt it?' This conversation takes place BEFORE Rey touches the lightsaber and has a revelation. The awakening mentioned by Snoke is clearly Force related, so is most likely related to Finn.
*This is further backed up that in the village on Jakku, Ren stops mid-stride and turns to look at Finn for a long time. As if he senses something in the trooper, but can't quite figure out what it is. If he later realizes it was a Force awakening then all the more reason why he's constantly pissed off that FN-2187 is getting caught up in the mix. Indeed, Finn's awakening here may be the Force going into him and he feeling the life all around him being snuffed out - shaking him out of his conditioning, '...souls crying out in anguish and suddenly being silenced' so to speak.
*Finn is an exceptional combatant. Like, ridiculously good. Phasma states in the canonical book tie in to the film, 'FN-2187 has the potential to be one of the finest stormtroopers I have ever seen.' And in regards to a training simulation, [says], 'FN-2187, your targeting was exemplary. According to the simulation, you fired your weapon only thirty-six times, scoring kills with thirty-five of those. You deployed one explosive, which resulted in the achieving of the objective and another six enemies killed. All of you should take your example from FN-2187.'
*Finn sucks with a lightsaber it seems, but he's almost certainly never trained with one and even makes it clear early on that its blasters where he's skilled and comfortable, suggesting if he has had any melee training it's not comprehensive. But the Force does not make one suddenly good at using a lightsaber, that's simply the product of training. The Force, rather, accentuates your skills, perception, reaction time etc etc - much like Anakin in a pod racer.
*And yet, despite being a lousy duelist with a saber, Finn does actually land a hit on Ren in snowy wood fight. This is pretty surprising, even with Ren seriously injured and perhaps over confident."
Beyondintodarkness believes the explanation for Finn being a janitor/stormtrooper is a simple one:
"We know the First Order has been kidnapping small children for decades to train as soldiers. However, as Kylo Ren points out, these are not clones. They have a normal rate of development, or semi normal. Unlike the clones, Finn has developed psychologically in a fairly normal fashion so even if they accelerated his growth physically it can't be by that much. So, the first order isn't likely training children vigorously until at least mid-late teens but now they have a problem, what to do with them in the meantime.
Give them crap jobs, that's what. Starkiller Base wasn't built overnight. We know that technology doesn't change rapidly in Star Wars and that the second Death Star likely began construction immediately following the first Death Star's destruction, so to completion we're looking at around 4 years start to finish, and that's reusing mostly the same plans from the first. So, scale that up to a planet and we're looking at at least a decade or two for Starkiller Base. Plenty of time for the First Order to stick Finn on there as a janitor when he was a child or teenager while he waited for training."
Graciasamigo sees true greatness in Finn, or maybe more accurately, true goodness:
"Looking at his character, he's trained from childhood as a bloodthirsty stormtrooper, and yet through his undeniable desire to do good, he shakes off the years of training and refuses to shoot unarmed villagers. And tried to help a fallen soldier.
Though at one point he became uncertain and frightened of the situation, and he tried to flee, his witnessing of the kidnapping of Rey filled him with such terrible regret that he abandoned his friend. This strengthened his convictions of what was 'the right thing to do.'
Depending on if Rey and or Kylo Ren flip flop to the dark or light side, Finn will remain true to the good natured side, he will fight hard for what is right, helping those even if he doesn't want to, and he will always see the good in everyone. In short, his conviction to goodness, will be stronger than the light side or the dark side of the Force. And he will rise as the true hero of the saga."
