Bill Cipher lounged back in the old, creaky armchair, his form slouched with an air of careless superiority. The flicker of his singular golden eye danced with the flames licking the fireplace, casting long, erratic shadows against the Mystery Shack’s weathered walls. Married. The word echoed in his mind, bouncing around like a loose screw rattling in a machine that was otherwise perfectly engineered. It was a strange concept—strange even for him. Bill Cipher, the all-powerful, all-knowing demon, now bound to something as mundane and human as marriage. Sure, he had gotten what he wanted—his freedom, a loophole out of the Axolotl’s sentence, a clever trick to escape being cast into some obscure, forgotten dimension. But the arrangement wasn’t just that. Not entirely.
A low chuckle rumbled from his chest, the sound tinged with something almost too human, a quality that made him sneer inside. He didn’t like it, this creeping humanity that slithered into his existence like an unwelcome guest. He had proposed this absurd, laughable idea of marriage because it had been, at the time, the simplest solution. The path of least resistance, the way to outwit forces greater than him. And yet… beneath that, deeper than the layers of deception he was so accustomed to weaving, there was a sliver of truth he couldn’t quite shake.
His eye flickered, narrowing slightly as he let the realization settle. If it weren’t for Dipper, if it weren’t for that irritating, stubborn, determined Pine Tree, the very notion of marriage wouldn’t have been considered for more than a second. It never would’ve been an option. No, if Dipper hadn’t been part of the equation, Bill would’ve happily disintegrated into the void, evaporating into oblivion before tethering himself to any other being. The idea of chaining himself to anyone else made his skin crawl.
But here he was.
He stretched lazily, watching as the firelight reflected in his golden eye, his thoughts drifting back to the absurdity of it all. Married to Pine Tree. His Pine Tree. The thought alone made a grin stretch across his face, though it didn’t quite reach his eye. How hilarious, how ridiculous it was to think that after everything—after the battles, the chaos, the trickery—he’d end up in this shack, sharing a bond as binding as marriage. He could feel the laughter bubbling up inside him, the dark amusement that came from how twisted fate could be.
His eye turned, resting on Dipper. The boy—no, the man, now—sat across the room, slouched in a chair with a book in hand, the light from the fire painting soft shadows across his face. His brows furrowed in concentration, completely oblivious to the storm brewing inside Bill’s head. He had no idea how much influence he had in this twisted deal, how his existence had shifted the scales in a way Bill had never anticipated. Bill had pitched the marriage as a necessity, a contract born out of survival and practicality. But if he was being brutally, painfully honest with himself, he knew that if it weren’t for Dipper—specifically Dipper—he would’ve found another way out. He could’ve found another way out.
Bill’s grin faltered for the briefest moment as he watched the human, the one person in this dimension—or any other, for that matter—that made him feel something other than the relentless monotony of omniscience. Something he wasn’t entirely ready to admit, not even to himself.
“Marriage of inconvenience, huh,” Bill muttered under his breath, a smirk tugging at the corners of his lips. It was what he had called it, a marriage born out of necessity, but deep down—even if he wouldn’t dare admit it aloud—he knew that was entirely the truth. There was something gnawing at him, buried deep beneath layers of chaos, arrogance, and centuries of insanity, that made him pause whenever he thought about it too long. That he didn’t truly mind being married to Dipper.
He leaned back in his chair, his golden eye lazily tracing the curve of Dipper’s profile as the human sat across the room, engrossed in whatever book he was poring over this time. Bill propped his chin on his hand, the smirk still lingering but softened by something more contemplative. His gaze was steady, lingering longer than it should have, as if there were answers hidden in the lines of Dipper’s face.
His Pine Tree wasn’t the same awkward, gangly kid he had met years ago. No, Dipper had changed. He had grown. At eighteen, Dipper had shed the innocence of childhood and become someone sharper, more confident—someone who could hold his own in ways that even Bill had to admit he found impressive. Begrudgingly at first, Bill had come to respect him. That respect, though, had quickly spiraled into something more. Fascination. That human had a way of seeing the world, of thinking, that caught Bill off guard. And fascination, well... that had turned into something far more dangerous, something far more compelling than Bill had ever anticipated.
His eye flickered with an intensity that belied the nonchalant posture he held. How had it come to this? The great Bill Cipher, the destroyer of worlds, the master of chaos, now sitting here, tied to a mortal by legal human conventions. If someone had told him this would happen, he would’ve erased them from existence without a second thought, probably with a laugh, too. The sheer absurdity of the situation was something even Bill found amusing. Yet, here he was.
But Dipper? Bill couldn’t erase him. Not even when he had the chance. Not even when the boy had the audacity to thwart his grand plans during Weirdmageddon, shattering his ambitions like they were nothing. Even then, even at the height of his frustration, there had been something about Pine Tree that made Bill hesitate, that made him want to keep the kid around, to watch him grow, evolve. There had always been something intriguing about him, something that clawed at Bill’s mind, pulling him in closer despite his better judgment.
Dipper was different. He wasn’t like the countless other mortals Bill had toyed with over millennia. No, Dipper had something more—something Bill had come to crave. Maybe it was the way Dipper looked at the world with an unrelenting curiosity, that razor-sharp intellect, that strange blend of skepticism and hope. Or maybe it was the fact that no matter how many times Bill tried to break him, to bend him to his will, Dipper always pushed back. There was a fire in him, a spark that refused to die out, and that… well, that was worth something. More than Bill had ever expected.
Bill’s smirk widened as his thoughts drifted. If he had been anyone else—any other being—he might’ve thought that what he felt was something akin to admiration. But Bill Cipher didn’t admire. He coveted. He desired. And what he desired, he took. Dipper was no exception.
Except Dipper hadn’t been easy to take. Bill had offered him a deal, one that no other being in the entire multiverse deserved. The kind of deal that had more implications than Dipper likely realized, though Bill was certain the kid would figure it out sooner or later. He always did. That was one of the reasons Bill liked him so much, after all. But the truth, the undeniable truth, was that no other human would’ve been worth the trouble. No one else would’ve made Bill consider this insane proposition. Dipper, though… Dipper was different, special.
Bill tilted his head slightly, his usual cocky grin softening, just a fraction, as he observed Dipper. The boy’s brow was furrowed in concentration, eyes skimming over the pages of yet another ancient tome. Whatever mystery he was unraveling tonight had him fully absorbed, his fingers idly drumming on the worn cover. Bill’s gaze lingered, tracing the lines of Dipper’s face, the subtle crease of his forehead, the way his lips pursed ever so slightly when he was deep in thought. There was something almost endearing about it—something that tugged at Bill in a way he wasn’t entirely comfortable with.
“You have no idea what you’ve done to me, do you, Pine Tree?” Bill muttered under his breath, his voice low, barely audible in the crackling quiet of the cabin. The words slipped out before he could stop them, a confession spoken only to the flickering shadows. He almost winced, as if saying it too loudly would make it too real, would force him to acknowledge the truth that had been gnawing at the edges of his mind for longer than he cared to admit.
Dipper glanced up at him, his brows lifting in curiosity. “Did you say something?”
Bill’s grin snapped back into place, the sharp, dangerous smirk that Dipper had come to recognize—one that always seemed to straddle the line between playful and menacing. “Just thinking out loud, kid. Nothing to worry your little mortal brain about.” His tone was as casual as ever, that familiar lilt of mockery woven into his words, but there was a flicker of something else behind it. Something Dipper, in his endless search for truth, might’ve caught if he hadn’t turned back to his book so quickly.
Dipper rolled his eyes, the gesture exaggerated but fond, as if he had grown used to Bill’s antics and the demon’s constant teasing. He settled back into his reading, but Bill’s keen eye caught the faintest twitch at the corner of Dipper’s lips. Was that a smile? Yeah, it was. Barely there, but enough to betray a small crack in the human’s usual stoic demeanor.
Bill leaned forward just a little, his eye gleaming as he watched Dipper pretend not to notice him. That smile—however faint—sent a spark of satisfaction racing through him, an odd warmth spreading in his chest that Bill would never openly acknowledge. He liked getting those reactions out of Dipper. A smirk, a glance, a raised eyebrow—anything that proved Bill could still get under his skin, even if only in the subtlest of ways.
But it was more than that, wasn’t it?
Bill’s grin faltered again, just for a heartbeat, as he let his gaze linger on Dipper’s face. You have no idea what you’ve done to me. The words echoed in his mind, louder now, more insistent. Dipper didn’t know—couldn’t possibly know—the effect he had on him. The way he had wormed his way into Bill’s thoughts, into the very fabric of his being, until it was impossible to imagine the universe without him in it. It was maddening, really, this pull that Dipper seemed to have over him, and yet Bill couldn’t bring himself to break free of it. He didn’t want to.
Leaning back in his chair, Bill let his thoughts drift, his eye narrowing slightly as he stared blankly at the ceiling. He had always been the puppet master, the one pulling the strings, manipulating people, bending reality to his will. Control had been his lifeblood, his very existence defined by the chaos he could sow. And yet, here he was, sitting in the dim glow of the Mystery Shack, not as the godlike being who could twist the fabric of dimensions, but as someone... bound. Not just by a contract, though. No, this was something far more intricate, something far more dangerous than any binding spell or legal document.
This was emotional. And it was beginning to tear him apart.
For the first time in his existence, Bill wasn't the one pulling all the strings. This ridiculous domestic arrangement, this so-called "marriage," had changed something. It wasn't just about escaping the Axolotl's judgment, or about securing his freedom from a fate worse than death. No, it was deeper than that. There was something about Dipper that made Bill want to stay here. Something about this absurd little dimension, with all its limitations, that made it appealing to stick around. And not for chaos, not for destruction, but for the human sitting across from him, engrossed in his book, blissfully unaware of the storm raging in Bill’s mind.
And that scared the hell out of him.
Bill Cipher, scared? The notion was absurd. Fear wasn’t an emotion Bill had any use for—he had never been afraid. He was the one others feared. Emotions, sentimentality, caring about someone other than himself? That was for lesser beings, for mortals and fools. But the more he sat there, watching Dipper in the soft firelight, the more he realized that something had shifted. He was feeling... something. Something he couldn’t define, something unfamiliar and utterly infuriating.
He hated it.
Bill gritted his teeth, running a hand through his messy golden hair as if trying to comb the thoughts out of his head. Every instinct screamed at him to reject it, to destroy the part of himself that was starting to care, to bury it under layers of chaos and cruelty. Yet no matter how hard he tried, that insidious little emotion wormed its way deeper, wrapping around him like an unbreakable chain. It was why he hadn’t wiped Dipper’s memory the moment the paperwork was done and moved on to another grand scheme.
Because for all his bluster, for all his claims that this was just another convenient deal, there was a truth gnawing at him, one he could no longer deny: Dipper had gotten to him. Somehow, this mortal, this insignificant human, had become important. The very thought made him want to laugh, to howl at the absurdity of it all. Bill Cipher, destroyer of worlds, master of dimensions, brought low by a human boy who wasn’t even fully aware of the power he wielded over him.
He leaned forward, his gaze sharpening as he stared at Dipper, who was still lost in his book. The kid had no idea, did he? He had no clue what he’d done, how deeply he’d gotten under Bill’s skin, how much influence he now held over the demon. Bill could snap his fingers, unravel the world, and yet… the thought of unraveling this, of tearing apart the tenuous bond they had formed, was somehow worse.
And that realization? That was the scariest part of all.
He clenched his fists, fighting the impulse to burn it all down, to break free from whatever this was before it became something more, something even more dangerous. But deep down, he knew he wouldn’t. He couldn’t. Because for all his bravado, for all the centuries of chaos he had lived for, there was something about this—about Dipper—that made him stay.
"You're such a hassle, Pine Tree," Bill said, his voice carrying an uncharacteristic softness, the sharp edge in his tone conspicuously absent. It was almost like he was speaking out of habit, but the venom that usually laced his words was missing, leaving something warmer—more familiar—in its wake.
Dipper looked up from his book, eyebrows furrowed in a mix of confusion and mild irritation at the insult. “What?” he asked, though his voice was more resigned than offended, like he’d grown used to Bill’s strange remarks.
Bill’s grin stretched lazily across his face, his usual predatory smirk tempered with something softer. The sharp edges of his smile, once dangerous and menacing, had softened into something almost... fond. His gaze lingered on Dipper, the glowing ember of his golden eye flickering with an emotion that was hard to name, even for him. "Nothing," he finally said, voice low, almost purring. "Just admiring how much trouble you're worth."
The words slipped out more naturally than he intended, and for a brief second, a hint of sincerity bled through the usual layers of sarcasm and mockery. He meant it. Dipper was a hassle, a colossal one at that, but in the way that made things... interesting. No one else had ever been worth the trouble. No one had ever made him feel like sticking around was worth it. But Dipper had changed everything.
Dipper gave him a long, searching look, clearly confused but unwilling to delve deeper. He wasn’t quite sure what to make of Bill’s strange demeanor, but he chose not to press the issue, opting instead to shake his head and return to his book. "You're so weird, Bill."
Bill’s chuckle was low and deep, the sound resonating in the dimly lit room like a distant rumble of thunder. His golden eye glowed faintly in the firelight, casting an eerie, soft glow across his face. "You have no idea, kid," he murmured, the words slipping out with a hint of mischief. But beneath that mischievous tone, there was something heavier, something Dipper couldn’t quite catch, but that Bill felt intensely in the quiet moments between his playful jabs
For once, Bill wasn’t lying. Dipper had no idea what kind of storm he had stirred within the demon, how much of a tangled mess Bill had become because of him. The great Bill Cipher, the embodiment of chaos, was tethered to something as mundane as feelings—and for Dipper Pines, of all beings. It was maddening and exhilarating all at once.
But Bill would never admit that aloud. Not yet. Not while there was still some fun to be had in watching Dipper try to make sense of it all.
