PROMPT: Billy is jealous of  Stu's relationship with you.

🔪🩸⛓️🪓💀🍷👻 ☎️🚬❤️‍🩹🃏🥀🕯️

The air in Stu's living room was thick with laughter and the faint scent of popcorn, leftover from some movie marathon that had long since turned into an excuse to hang out and do anything but actually watch a movie. Stu had abandoned the couch long ago, now sprawled across the floor with [Y/N] beside him, playfully wrestling over the remote as she tried to find something other than the horror flick he insisted on watching.

Billy watched them from his seat on the couch, arm loosely draped around Sidney's shoulders. It should have been easy enough to ignore the two of them—they were always like this, always bouncing off each other with that effortless chemistry that came from years of friendship. But tonight, there was something about their back-and-forth that gnawed at him, a subtle, nagging irritation he couldn't quite shake.

"[Y/N], just let me pick," Stu whined, stretching out his arms in an exaggerated pout. "I swear, it'll be good this time!"

[Y/N] gave him a playful shove, rolling her eyes. "You said that last time, and I'm pretty sure we ended up watching some horror B-movie with exploding heads."

Billy couldn't help but smirk, though the amusement was short-lived as he caught the way Stu leaned closer to [Y/N], his smile widening as he brushed a stray strand of hair behind her ear.

The casual, thoughtless intimacy of the gesture made Billy's jaw tighten. It was stupid—[Y/N] was Stu's best friend, and she'd been around the group forever. But tonight, for some reason, every small touch, every shared laugh, felt like a deliberate provocation.

"You two ever gonna decide, or are we just sitting here all night?" he muttered, trying to keep the irritation out of his voice.

[Y/N] looked over her shoulder, her usual easygoing smile faltering for a moment as she caught Billy's expression. "I'm trying to save us from Stu's terrible taste in movies. Believe me, I'm doing you all a favor."

Stu flashed him a grin, clearly oblivious to the undercurrent. "You got anything better to do, Loomis?"

Billy felt Sidney's hand squeeze his, as if reminding him to relax. But her touch did little to soothe the knot of frustration tightening in his chest. He glanced down at her, catching the warmth in her eyes, and forced a small smile, brushing his thumb over her knuckles. He didn't want her to pick up on his mood—especially not when he didn't entirely understand it himself.

But when he looked back up, [Y/N] was laughing at something Stu had whispered to her, leaning closer as Stu threw an arm over her shoulders, pulling her into a side hug.

He could feel his blood simmering as he watched them, his mind spiraling through the thousand tiny moments he'd seen between them: the way they always seemed to find each other in a crowd, how [Y/N] laughed at Stu's ridiculous jokes, how she rolled her eyes but always went along with his antics. And tonight, something about it felt...different. Or maybe he was just seeing it differently.

As if sensing the shift, Stu finally looked over, catching Billy's gaze with a raised eyebrow. "Hey, man, you good? You're being, like, unusually silent."

Billy forced a laugh, though it sounded a bit too sharp. "Just wondering when you're gonna let us watch something that isn't trash, Macher."

Stu feigned offense, placing a dramatic hand over his heart. "You wound me, Loomis. My movie taste is impeccable."

"Oh, please." [Y/N] snorted, leaning back against Stu as if it were the most natural thing in the world. "Impeccable like a dumpster fire."

Billy could feel the jealousy gnawing at him, irrational as it was. He had Sidney—sweet, perfect Sidney—sitting right there next to him, and yet, his gaze kept drifting back to [Y/N], drawn to her in a way he couldn't quite rationalize. It wasn't even about wanting her; it was just the fact that, for once, she wasn't looking at him. All her attention was on Stu, and the realization twisted something sharp and unexpected inside him.
