Currently watching 1923 (despite knowing how it ends because of my mother) and I feel like the Spencer/Alexandra relationship would make a good Clegan fanfic.
(gonna use buff gale for this)
Gale, who's haunted by the war, now lives in Africa and travels from village to village, travel group to travel group, hunting predators that attack them for money. He meets Bucky by chance, who's having a destination wedding of sorts at a lodge-ish place. He doesn't love his fiancé, which is obvious by the way he's flirting with Gale. He's marrying the manbecause of familial pressure.
Gale tells him that he's leaving the next day for his next job, and the next day Bucky chases after Gale's car. He jumps in and tells his fiancé to find someone who loves him. They fall in love on this trip, getting engaged while looking at an early footprint of man. Elephant rams their car on the way back, and they get caught in a tree for the night with a pride of lions feasting on the elephant, before turning their attention to them. They then head to a beach, before reading letters that Gale's aunt wrote to him, insisting that he needs to come home.
The first boat they board gets overturned, then are rescued by a ship that Gale was lucky enough to radio to before getting overturned. They get married on the ship that night, and the next day they get dropped off in Sicily until their next boat. They happen to run into Bucky's ex-fiancé at the restaurant they eat at. He also happens to be on the same boat as them. Stuff happens, and the ex ends up challenging Gale to a duel. Gale doesn't want to, then the guy calls Bucky a whore, then he fights. With swords they duel, and Gale keeps disarming, then the guy pulls a gun, Gale dodges, and the guy ends up jumping off the ship by accident, then drowning. Because of this, Gale ends up being eventually ordered off the ship by the guys father because he's rich. Bucky yells off the ship that he'll meet Gale in Wyoming.
Gale gets a Job on a freighter, where he befriends a guy (could be anyone from the cast, or an oc) after saving him from a guy sexually assaulting him, and also a suicide attempt. He's working to America.
Now, in the show, Alexandra is pregnant. Now, this whole thing can be an omegaverse thing, since this is set not long after ww1, if you want, or it can just be a regular ole no homophobia au.
Anyway, Bucky is being held his ex's family in London, who's trying to get him to annul his marriage with Gale. I forgot to mention, that he met his rich bestie who helped lessen the charge on Gale (maybe this is Marge or Helen or something.) They make a plan to make secure a passage to America for Bucky (and if omegaverse, tells Helen/marge/whoever he's pregnant)
They sell some of Bucky's expensive belongings, planning to lie to his parents about where he is, and plan to book him a second class ticket on the first ship out of there.
(while this is happening Gale and the guy he saved started a fight club on the boat for Gale to earn enough money to get to his family. Then has a run in with the mafia)
Bucky ends up on tourists class. If omegaverse, Bucky writes to Gale about his trip and wanting to have more children with him. He ferries to ellis island, where he's checked for sickness and such because he has no travel papers. If then omegaverse and he's pregnant, he faces some anxiety when getting a more extended medical check up, as he hears pregnant people get sent back. The checking for venerial diseases is hard for him, and despite not showing, it gets found out he's pregnant. The whole process is actually quite difficult for him if he is.
With the help of an elderly man he gets to grand central station to head to Wyoming. He gets robed there, almost missing the train which he has a shared room ticket for.
On a train, while working off a way to be fed, as he had no more money, Bucky gets sexually assaulted by a guy. The first time, he accidentally spills hot water on the guy, and he forces Bucky to wipe it off his pants, holding his hand against his dick. The second time it happens, he defends himself, almost getting arrested for it, until a very nice couple (Ken and Rosie I think would be nice) stands up on his behalf, because they saw what happened. He needs to make a statement the next day and the train is canceled, so he has nowhere to go. Ken and Rosie invite him to stay with them in Winnetka (or something) after running into him and seeing him cry. He shares his love story with the two of them, and Ken, missing adventure as he grew up on a farm, and Rosie, who loves Ken dearly, decide to help Bucky get to Wyoming.
Now, when it gets down to it, I don't want to give Ken and Rosie the same fate as the nice rich couple in the show. Now, either they ignore the gas station attendant's advice like in the show and get caught in the storm, but they prepared for it with shit they could get at the gas station, and they do the fire thing that Alex did. Or, they listen to the attendants warning, sell the car, get train tickets, and go to Wyoming that way. Maybe they get caught up in the family BS, and if omegaverse, he gives birth and interrupts the BS. Rosie and Ken end up buying a plot of land there for vacationing, as well as maybe a firm there in the event they move there full time or maybe get caught in an early winter or something. Gale and Bucky's child(ren) grow up excited to see the Rosenthal's and their child(ren)
