you asked for some sledge/snafu headcanon here's some?
you know what, i don't think sledge and snafu end up shacking up together. i think they live near each other and they visit all the time and they go out on man dates every week but i don't think they live together. snafu would be distinctly uncomfortable living beyond his means on someone else's money and sledge wouldn't be the type to "slum it" nor would it befit his station.
i'm not even sure if they're still "romantically involved" if you'll forgive the phrase. i don't know how they'd work it out. i have less of a case for them being interested in each other as people than i do for them being interested in each other for what they represent. it's a matter of psychological dependence vs love, goddamn this is gay as shit. sledge/snafu have a really strong codependence, but i'm not sure that would carry on for the rest of their lives. at some point, their respective personal issues straighten out. sledge stops being angry at everything, snafu stops hating everything. what have they got to hold them together other than that? once their little codependent bubble breaks open and other people start existing again, what makes them choose each other?
i don't really see it, anyway. i think after they stop needing each other, everything else just kind of fades off too. i think they're still really good, unlikely friends, but sledge eventually gets married, has kids, the like. snafu is everyone's cool uncle, and maybe he finds a creole girl with a really strong personality and a fantastic smile, or maybe that's a boy, or maybe he just disappears into the morning one day and lives on only as a figment in urban legends and broken bar stools.
no one will ever remember him growing old. he'll turn up somewhere, years down the line, and sledge'll get a call from somewhere in minnesota of all places and roe'll get one a couple hours after that and he'll have been dying for a while but didn't tell anyone, and sledge'll yell at him and roe will look disappointed, but he'll die with his friends by his bed and that will be his good death. he won't mind that.
there may or may not be a string of wild-eyed, wiry haired children littered across the nation. that's always a possibility
ive spent a month looking at this. thank u. quite hilarious tho i mean to get a headcanon which goes something like here is an analysis of why your fav dudes have no future together LMAO i agree tho ok. tbh ive really liked the idea of them staying as friends and parting their ways at some point. its bitter but it makes it.. more special in a way. it adds a unique sort of value to the relationship. it had heavily transformed but its still there, the connection. love. its nice. gives hope.
