contrary to popular belief, barty DID reunite with evan in the afterlife, but due to the dementor's kiss, he was only a shell of who he used to be
he lost everything that made barty barty
evan noticed, of course, but never really cared. obviously, he was sad about how things turned out, but in his eyes, barty was barty. his barty, and nothing could change that.
when barty thought of his past, he could only remember the extremes of it. his hypersexual tendencies, his chaotic and destructive persona, his all consuming love for evan.
so, he created hornkus binglefuck (reggie chose that nickname), an "alter ego" of sorts, from what he could remember of his past self, and tried his best to embody that persona, simply because he couldnt take the pain in evan's eyes whenever he looked at barty
evan hated hornkus binglefuck so much, because that wasnt barty. sure he was chaotic and outgoing and lowkey evil, but that was the barty everyone else saw, that was the persona barty forced himself to be. his barty was soft, gentle, passionate.
his barty would softly stroke his back after rough sex, whispering sweet nothings into his ear. his barty would sneak the two out of hogwarts just because he noticed evan was feeling overwhelmed. his barty took his time and listened to whatever bullshit evan was ranting about that day. his barty was his, and his only. not some persona, but himself, raw and unhidden. he wouldn't have to hide behind false words and emotions with evan, never.
so, one day, evan sat barty down, and explained to him oh so softly, because he knew barty was still fragile, no matter how much he tried to hide it, and he told him. he told him everything about his barty, and how he didn't have to pretend around him, and how much he loved him, his lack of a soul and true happiness included.
and barty broke down, and Evan held him, just like how barty held him during their hogwarts days. and barty never pretended around him anymore.
