Dumb (and by dumb, I mean amazeballs) movie.

• Poe hanging around two giant space puppies more often than not, but being completely blindsided when Jess refers to Rey and Finn as his. And then smirking and thinking “damn right they are.” 
• Finn not being terribly bothered by how strict his doctor and nurse are, because they’re not mean, and it’s structure. He’s free, but he needs that structure now that he’s not running on sheer adrenaline and while trying to find his fit with the Resistance. He can’t break a lifetime of habits in a few weeks, but he can take baby steps.
• Poe having low key nightmares about Kylo Ren violating his mind, and waking up to find Rey standing over him. He accidentally kicks her in the gut the first time and it’s all a big mess, but eventually he just gets used to waking up to her being there and she gets it. 
• Finn making friends with Snap Wexley and Admiral Statura, first because they’re going over the information Finn can give them and cataloging this knowledge, and then because Snap gets the bright idea to teach Finn how to play poker. “You have your people, and then you have your poker buddies, Finn. And your poker buddies will make sure Poe doesn’t fleece you for the shirt off your back, the rotten shark.”
• Snap introducing Finn to fire whiskey. 
• Poe laughing at Finn’s first hangover, but then getting him a painkiller and cuddling with him.
• Finn trying sugary foods for the first time and loving them.
• Snap realizing he can bribe Finn with candy, and ruthlessly exploiting it to win his prank war with Poe.
• Poe teaching Finn to kiss, because his guy is ridiculously eager, but ridiculously awful at it. Not that Finn would have had a lot of time to practice in the First Order. Besides, Poe might have a teeny, tiny possessive streak, and be stupidly pleased he gets to teach him.
• Rey being so absorbed with her Jedi training, and trying to figure out the Force and “be at one with it”, that it takes Poe and Finn some time to realize she has some capital I issues. 
• Poe and Finn not figuring out two of these Issues until they’re sent on a rescue mission with her, Snap, Jess Pava, and fellow First Order deserter, Officer Phasma, to bust out Admiral Akbar. Namely that A) Rey can’t swim AT ALL and they crash land in a lake, and B) Rey is utterly ill-equipped to deal with the winter planet they’re on. (Which really, they should have thought about this sooner.)
• This leads to a comedy of errors where Jess and Phasma have to go free the Admiral and rendezvous with them at the exit point, and Snap and Finn securing the exit point while Poe has to get Rey across that channel, clinging to his back like a baby monkey because the water is deep and there’s only a tiny underwater ledge they can inch by on, and she’s terrified. (And hypothermic and turning an alarming shade of blue.)
• Finn, however, is very gallant and dashing and being an utter boss in making sure the exit gets secured and Poe and Rey are safe. Poe’s not even going to lie, he’s very turned on.
• Rey being utterly mortified once they get back to base, and Finn refusing to let her be embarrassed, because he’s learned that’s what a team and a family are for. Covering your back when you’re down.
• Finn learning astromech so he can understand what BB-8 keeps saying, but refusing to give up their special thumbs up signal. Poe realizes he’s about to be in trouble when he walks in on the two of them doing that.
• Lt. Connix and Jess taking Rey out on leave trips, because Rey needs friends and Rey is a big dumb space puppy who hasn’t realized that Finn and Poe are not just friends, and that maybe she needs people to talk it out with that aren’t a Jedi master or the objects of her affections.
• Rey can drink them both under the table, because the only alcohol back “home” was the equivalent of 100 proof moonshine, and you have to get used to it early.
• Then they realize she doesn’t even know she’s been given an account with credits.
• Lt. Connix and Jess realizing Rey might have an Issue about food, because she uses all of her credits to buy packs of really awful food rations, and she gives them out to people she cares about.
• Poe and Finn have several packs of awful food rations, but they eat them proudly because they realize Rey is a big dumb space puppy and giving food is the highest form of showing affection she knows.
• Poe was so very wrong. Rey is a ridiculously awful kisser. Still, that means there’s just that much more practice time for him and Finn.
• Finn wrangling the other two into bed the way he likes it, so he’s the one facing the door. If someone comes in for them, they’ll have to get through him first. Besides, Rey’s softer, and gets cold at night. And if she’s in the middle, Poe’s arm settles around Finn’s waist at the perfect level that makes him feel safe, too.
• Poe realizing that while courting is definitely a thing where he grew up, and with other cultures on the base, Finn and Rey have no clue what it is, and dammit, his dumb space puppies deserve to be courted properly.
