One line in @themandalorianwolf‘s meta about Finn and his relationship with his past struck a cord with me, but it’s rather tangential to the topic so I’m hiving off.
The line is this one:
[Finn] had no clue that Poe would want to go back to Jakku and probably assumed Poe would go directly to the Resistance base…
Because yes, this is exactly what Finn would expect to happen when he sat down and planned his escape. That Poe flies directly (or maybe in a circuitous route) back to the Resistance.
Which would mean what precisely?
That Finn isn’t just trying to escape, but defect? Which puts the first reason he gives Poe “It’s the right thing to do” in a bit of a new light, he’s trying to sell himself as a potential Resistance fighter?
Does Finn expects to be taken as a prisoner of war, being an enemy soldier and all.
Obviously things does not go the way Finn expected them to and he had ample time during his trek through Jakku’s desert to rethink his plan and come up with a new one which was “get as far away from the First Order as possible”.
Sensible one too, but thinking about it I doubt it would be his initial one. Unless he thought he could talk Poe into dropping him off somewhere en route. But he’d also know that he would not be able to count on that, that he in a very likely scenario would end up in the hands of the Resistance and/or the Republic.
What did he think would happen to him then?
I don’t think he was thinking that far, at least at that very urgent moment. He talked about getting out of the system altogether, and not about the destination. That was the first thing on his mind, getting away from the First Order rather than to anywhere. Given his later actions I think it’s probable that he wanted to be dropped off and to keep going all the way to the Outer Rim. He also proved to be eminently persuadable on this point, however.
That’s why it’s interesting to think what might have happened if Finn and Poe had not been separated and Poe had tried to talk him into staying with the Resistance, or at least being thoroughly debriefed before he moved on. Poe would not have pulled a Rose and forced Finn to stay, and like Han he’d have understood and sympathized with Finn’s desire to get away. But Poe is also a Resistance fighter, and a spy. Imagine him telling Finn that he can make a difference:
“Buddy, I feel you. Getting away from those guys was good for my health and longevity and I’m guessing it’ll be good for yours, too. You did me and the Resistance a solid, and I’ll fight anyone who blames you for wanting to go. But before that, could you hear me out? You’re smart guy, Finn, and you’re right: if it’s one person alone against the First Order it’s either run or die. But if you’re with other people there’s a third choice: Fight back, together. You don’t have to be alone anymore.”
I remember reading a meta that said Finn was running largely out of despair, because he thought there was no fighting back against the First Order. If Poe, someone who had been doing exactly that, had talked to him? Who knows.
