I don’t know why but the idea of a soulmate AU between Billy, Steve and Eddie captivates me, especially with the idea that Billy unknowingly gets Steve and Eddie to find out that they’re soulmates. Either in a modern AU where Billy’s a big fan of Corroded Coffin and Steve just managed to get a free ticket or something or in a canon AU where Billy and Steve are friends who want to smoke a little something so they buy from Eddie or Steve picks up the kids from Hellfire and one of them notices the marks match, I don’t really care how but I just want to explore the hurt and comfort of that.
Can you imagine Billy pining away, forever in love with the idea of his soulmate being the one who’ll save him from his situation given that’s what happened to his mom and he finds out that his crush is his soulmate but doesn’t want to tell him yet until he’s made something out of himself, until he’s deserving of love and all of a sudden, he finds out that his soulmate found his soulmate and it wasn’t Billy?
Imagine Steve happily dragging Eddie with him who already looks besotted with Steve and they show Billy the mark that he’s memorized from seeing it in the mirror thousands of times and as soon as he sees the smiles on their faces and the look of wonder in their eyes, he knows for a fact he can’t ruin their happiness. He isn’t selfish enough to do it even others would say he was and all he could do was pretend to be happy and smile at the happy couple.
Imagine Billy pulling away, either out of fear he’d inadvertently ruin their relationship or because he couldn’t stand being surrounded by what he couldn’t have and the kids weirdly enough noticing and trying to figure out what’s wrong. It doesn’t help that Neil’s always been bitter about soulmates and he loved rubbing it in Billy’s face how worthless everything regarding soulmates and soulmarks was. Billy used to be able to ignore it in the hopes of finding his soulmate but now, he knew the truth.
The kids come to a different conclusion, not realizing it was something regarding soulmates but instead, about Neil’s treatment of Billy. If canon, it would be El spying on Billy and seeing him being beaten into a pulp by his dad but in a modern AU, it would the aftermath wherein Max would ask Steve to come visit Billy and he drags Eddie along with him.
Either way, Steve and Eddie find out about the abuse that Billy’s been suffering through and the guilt that Steve felt was immeasurable for not seeing what his best friend was going through, too busy with being in love with his soulmate. With Hopper’s help, they get Neil behind bars but Billy’s a wreck and he needs people to take care of him.
Steve refused to leave Billy alone in the trailer while Max went to school and Susan went to work so he offered to have Billy move in with him and Eddie so they could take care of him. Since Steve only worked part-time and Eddie was in the same year as Billy and could drive them to and from school, it made a lot more sense than leaving him to his own devices.
Billy thinks he’s in a new level of hell as time goes by because getting to know Eddie and seeing everything he can’t have was absolutely painful and heartbreaking on another level. Being surrounded by their care and affection when he’s barely known it his entire life hurts on another level he can’t exactly describe but it’s a pain that hurts so good that he can’t exactly say no to it. His only saving grace is that his mark was casted over due to Neil’s last temper tantrum and there was no way that the boys would get to see it.
Months pass of Billy falling more and more in love with his soulmates who are already in love with each other and it hurts so good. Steve and Eddie never make him feel like an outsider the entire time he’s there but sometimes, his touch starvation reminds him of just how much he’d love to be squeezed in between them in any way possible.
Graduation comes and goes and Billy refused to let his father take his achievements away so he graduated valedictorian, dragging Eddie kicking and screaming past the finish line to graduate. Billy gets to make his speech, loudly supported by everyone and he makes sure to thank his newfound family for all of the support they’ve given him.
Of course, graduation wouldn’t be complete without a graduation party so they all get drunk and party in Steve’s house to celebrate six graduations especially Billy and Nancy who graduated valedictorian and salutatorian respectively. Both Jonathan and Nancy planned to go to the same college in Chicago while Robin and her girlfriend, Heather were heading to California soon. Billy had also gotten into the same college but he wasn’t sure about going because he’d be leaving so much behind, including his soulmates.
By now, Billy was in love with both of his soulmates and unbeknownst to him, they were both plently enamored with him and they’d been trying to build up the courage to ask him out. The party had been slightly delayed because Billy was getting his casts off about a week after graduation and they wanted to do shots, something that really wasn’t advisable with a cast.
Billy had planned to initially conceal his mark using makeup but a large part of him knew that it didn’t matter since Steve and Eddie were happy anyway so he didn’t bother. After all, both Steve and Eddie loved to show off their marks at every opportunity and no one gave a shit about Billy. Somehow, Billy had managed to keep his mark a secret from everyone but he knew Heather had some suspicions.
After some time, the drinking games start and somehow, Billy’s mark is revealed either in a dared striptease or by accident during a dare and it quickly sobers him up. He doesn’t notice at first but then Robin drunkenly pointed out that they had matching marks and the sober gaze of Eddie was too sharp for Billy to meet, instead choosing to run away, stumble to his car and hit the gas to the quarry.
It’s only there that he allows himself to breakdown and to mourn the end of what was a good friendship he had going on with his soulmates because he was sure they would want nothing to do with him now. He’s only just begun to run out of tears when he hears the telltale sound of Eddie’s van, meant to drive Nancy, Jonathan, Heather and Robin home later but was most likely currenly holding the last people Billy wanted to see.
For a moment, he considers running again but his Mama didn’t raise no coward, so he wipes his tears and stands his ground. Steve was a lot drunker than Billy was when Billy had left but it seemed he’d sobered up during the ride because he was clear-eyed when he was grabbing Billy and making sure that the blond wouldn’t run away.
Steve and Eddie trapped Billy in between them, in what seemed like a mockery of his fantasies only to have them play out right in front of him. Never in his wildest dreams did he think that his soulmates would tell him that they wanted him, that they loved him and wanted to take care of him and love him. Sure, it was after an argument about why Billy felt the need to hide but he had expected rejection or at the very least a mutual ignorance of his mark. He’d never considered it a possibility but the two were convinced to try and convince him to give them a chance.
After more than a few tears and attempts to get them to realize they were better off without Billy and his baggage, Steve and Eddie stubbornly managed to convince Billy to try with them. A few kisses convinced Billy to leave his car behind so that they could get it in the morning but for now, Steve and Eddie wanted him in Eddie’s van so they were sure he wouldn’t run.
The entire ride, Billy’s mind was trying to convince him that Steve and Eddie were better off without him, that he didn’t deserve this and that he was a fraud ruining a perfectly happy couple but Steve instinctively knew something was up and he’d had Billy laid across his lap with his hair being stroked to keep the bad thoughts away while Steve affirmed Billy of all of their feelings towards him.
Halfway through the ride home, Billy was asleep and Steve had no problem carrying the younger boy into their bed so that they could finally hold him the way they wanted to. Billy had long since told them of how lonely he felt in his room but as much as they had wanted to invite Billy to literally sleep with them, they hadn’t wanted to cross any boundaries.
Tonight though, all Steve and Eddie wanted to do was to fall asleep holding their newly found soulmate. Billy awoke to Steve’s warmth cocooning him and Eddie coming in to wake him with breakfast in bed. After a hearty meal, Steve and Eddie asked if they could court Billy to show him how serious they were about their feelings for him and Billy found that much like before, he couldn’t say no to his soulmates.
Months passed with Steve and Eddie constantly trying to prove their love of Billy who eventually concedes and moves in with them in the master bedroom. It isn’t long until having Billy in between Steve and Eddie is a norm and no longer a fantasy for Billy and he realizes just how much he didn’t let himself have when he hated himself. With Steve and Eddie’s love, they helped Billy realize he was always worthy of love, care and devotion and that they were ready to spend the rest of their lives together reminding him of that fact.
