The silence that followed their greasy, unnerving meal felt heavier than the food in their stomachs. Jill watched as Sarah gathered the crumpled paper bags and cardboard boxes, her movements efficient but lacking her usual energy. The cheerful clatter of dishes being loaded into the dishwasher was a hollow sound, a pantomime of domesticity that did nothing to fill the space between them.
“I’ll take the trash out,” Sarah said, not meeting Jill’s eyes as she tied off the plastic bag.
“Okay.”
Jill stayed at the table, tracing a pattern in the condensation left by her water glass. The craving for the chicken was gone, replaced by a dull, greasy satisfaction and a sharper, more persistent anxiety. Was it them? The question was a loop she couldn’t escape. If it was, what did it mean? Were they just... bored? Playing with their food sources? The idea that her own desires could be hijacked for something as trivial as fast food was somehow more violating than the physical intimacies. One was a choice, however wild. The other felt like theft.
Sarah returned, the cool evening air clinging to her sweater for a moment before the apartment’s warmth absorbed it. She leaned against the kitchen counter, arms crossed.
“We should probably ... talk about it,” she said, her voice tentative.
“The chicken?” Jill asked, though she knew that’s not what Sarah meant.
“Everything. Last night. The ... the cuddle puddle on the rug. The chicken. All of it.” Sarah’s brow was furrowed, the bubbly confidence from the esoteric shop a distant memory. “We’ve been just reacting. Letting it happen. Maybe we need to ... I don’t know. Not react for a bit.”
Jill looked up, a flicker of hope cutting through the unease. “You mean, take a break?”
“A night off,” Sarah nodded, the idea gaining strength as she spoke it aloud. “A totally normal, creature-free, journal-closed night. We just be Jill and Sarah. Sisters. Not ... whatever we’ve been becoming.”
The relief was so profound it felt like a physical unclenching in Jill’s chest. “Yes. God, yes. A night off.” She let out a breath she felt like she’d been holding for days. “We just clean up, make some normal plans for tomorrow, and go to bed. Like regular people.”
“Exactly!” Sarah pushed off the counter, a bit of her old animation returning. “We’ve been letting this thing consume us. We need to prove we’re still in charge. That we can walk away.”
It was a simple, beautiful plan. A declaration of independence. They finished cleaning the kitchen with a new, shared purpose, wiping down counters and scrubbing the frying pan with a vigor that felt cleansing. The ordinary tasks were a shield against the extraordinary.
As they worked, the conversation turned, carefully, to the future. The immediate future. The next twenty-four hours.
“I was thinking,” Sarah said, rinsing soap suds from her hands. “Ben texted earlier. There’s that new superhero movie at the Cineplex. The one with all the explosions. He asked if I wanted to go tomorrow night.”
Ben. Sarah’s on-again, off-again ... something. A music major with a perpetually charming smile and a commitment phobia the size of a concert hall. He was fun, uncomplicated, and existed in a world that had no knowledge of bioluminescent symbiotes. He was, in a word, normal.
“That sounds good,” Jill said, meaning it. A date. A movie. Popcorn. It was a perfect, human distraction. “You should go. Have fun.”
“What about you?” Sarah asked, drying her hands on a towel. “You can’t just sit here alone with your thoughts. That’s how you end up ... you know. Brooding.”
Jill smiled faintly. “I have a life, you know. I was going to hit that used bookstore downtown tomorrow afternoon. The one with the cat. And maybe after, just walk around the mall. Window shop. Be utterly, boringly mundane.”
“The one with the grumpy orange tabby?”
“That’s the one.”
“Perfect.” Sarah’s grin was genuine now. “See? We have plans. Normal-people plans. We’ll go to bed early, get up, have a normal day, and do normal things. No boxes. No journals. No... anything.”
The pact was sealed in the clean, lemon-scented air of the kitchen. The tension that had gripped them since morning didn’t vanish, but it receded, pushed back by the sheer, stubborn force of their decision. They were taking back control.
The rest of the evening passed in a quiet, determined imitation of their old routines. They watched an episode of a baking competition show on TV, making snarky comments about the contestants’ soggy bottoms. They laughed, and for a few minutes at a time, Jill could almost believe the laughter was real, untainted by the memory of shared, desperate gasps from the night before.
But her eyes kept drifting, pulled by a silent gravity, toward the hallway that led to their bedrooms. To where the boxes waited.
When the show ended and yawns began to punctuate the silence, they both knew it was time. The final test of their resolve.
“Right,” Sarah said, standing up and stretching. “Early start for a day of normalcy.”
“Right,” Jill echoed, clicking off the TV.
The walk down the hall side-by-side felt ceremonial. The apartment was quiet, the only sound the soft scuff of their socks on the hardwood. At Jill’s door, they paused.
“Okay,” Sarah said, her voice dropping to a whisper, as if the boxes had ears. “We go in. We get ready for bed. We ... acknowledge them. But we don’t open them. We don’t write in the journals. We just ... go to sleep.”
“Acknowledge them how?” Jill asked, a thread of nervousness returning.
“I don’t know. Just ... look at them. Tell them—tell ourselves—that tonight is off. A reset.”
Jill nodded. It felt silly, like talking to a pet plant, but also necessary. A line in the sand.
Sarah gave her a quick, tight smile and then turned to her own door. “Goodnight, Jill.”
“Goodnight, Sarah.”
Jill pushed her door open and stepped into her room. It was exactly as she’d left it that morning—bed unmade, a sweater draped over her desk chair, a few books stacked haphazardly on the nightstand. And there, on her bookshelf between a well-worn fantasy novel and a book of poetry, sat the wooden box.
It looked so ordinary. A simple, polished cube of dark wood with a small brass latch. It held no glow, emitted no sound. It was just an object. Yet her pulse picked up a fraction as she looked at it. The memory of it opening from the inside, of the velvety, violet-tinted creature flowing out to join its twin on the rug, was vivid and cold.
She changed into her pajamas—soft cotton shorts and an old, faded t-shirt—methodically going through the motions of her bedtime routine. She washed her face, brushed her teeth, her movements automatic. All the while, her awareness was fixed on the box in the periphery.
Finally, with the lights off and only the faint glow from the streetlamp outside her window illuminating the room, she stood before the bookshelf. She wrapped her arms around herself, a self-soothing gesture.
“Okay,” she whispered, her voice barely audible in the dark room. “You stay in there tonight. We’re taking a break. No ... no feeding. No nothing. Just ... be a box.”
The box, of course, did nothing. It sat there, inert and silent. Jill felt a flush of foolishness heat her cheeks. Talking to a box. Great.
But as she turned to climb into bed, a strange thing happened. A thought, clear and unbidden, popped into her head. It wasn’t a craving for food or a surge of arousal. It was simpler, quieter.
It’s lonely in the dark.
The thought was so sudden, so distinctly not her own, that she froze, one knee on the mattress. It wasn’t spoken in a voice. It was just a concept, fully formed, that appeared in her mind like a subtitle on a screen. A feeling of quiet, patient solitude. Not a demand, not a manipulation. Just a ... statement.
Her eyes snapped back to the box. Her breath caught. Was that...? Had it...?
No. She shook her head, physically rejecting the idea. You’re exhausted. You’re paranoid. You’re imagining things because you’re freaked out. It’s your own brain, making up stories.
She forced herself to get into bed, pulling the covers up to her chin. She stared at the ceiling, her heart hammering against her ribs. It’s lonely in the dark. The phrase echoed. It did sound like something she might think, in her more melancholic moments. That was it. It was just her own subconscious, projecting onto the silent box. That had to be it.
She closed her eyes, willing sleep to come. But the silence of the room felt different now. It felt ... attentive.
Across the hall, Sarah stood in the middle of her room, staring at her own box where it sat on her white dresser, next to a collection of perfume bottles and hair ties. Her room was brighter, more chaotic than Jill’s—posters of bands on the walls, clothes half-spilling from her closet, a ukulele propped in the corner.
She’d already changed into her sleepwear—an oversized t-shirt that fell to her mid-thigh. Her resolve, so firm in the kitchen, was wavering now that she was alone with it.
“A night off,” she said aloud, her voice firmer than Jill’s whisper had been. “You hear that? No funny business. We’re closed for renovations.”
She waited, half-expecting a response, half-fearing one. None came. The box was just a box.
But as she stood there, a feeling washed over her, subtle and warm. It wasn’t a thought, exactly. It was more like an emotional tone, a color. It was a sense of... contentment. A simple, peaceful gladness that she was there, in the room. That it could sense her nearness. It was the emotional equivalent of a cat purring because you’re in the same room.
Sarah’s brow furrowed. She rubbed her arms, suddenly chilled. That’s not me. Is it? She was glad to be taking a break. She was feeling more in control. Maybe this was just her own relief, magnified by her tired mind.
Still, the feeling was so distinct, so separate from her own jumble of anxiety and determination. It felt like a soft blanket of calm being gently draped over her shoulders.
“Stop it,” she muttered, to herself or to the box, she wasn’t sure. “No feelings. No communication. Box. Stay box.”
She turned her back on the dresser and climbed into bed, determined to shut it out. She scrolled through her phone for a few minutes, looking at pictures of dogs on social media, forcing her brain onto a neutral, cute track. The sense of warm contentment faded, but it left a residue, a confusing aftertaste of connection that made her vow of a night off feel strangely like a rejection.
After ten minutes, she put her phone down. The room was dark. She could just make out the silhouette of the box on her dresser. A part of her, the part that had been so eager in Elara’s shop, the part that had thrilled to every new sensation, felt a tiny, guilty pang.
It’s just for one night, she told herself. We need this.
She closed her eyes. Sleep was a long time coming.
The next morning arrived grey and drizzly. Jill woke feeling surprisingly rested, the deep, muscular ache from two nights prior finally faded to a faint memory. For a glorious few seconds upon waking, her mind was blank of everything but the sound of rain against the window.
Then she remembered. The chicken. The pact. The thought that had slithered into her mind: It’s lonely in the dark.
