Chapter 28 – The Welcome Party and the Pinky Promise
The coffee in my hand was still warm, which was honestly the most normal thing about my current situation.
I stood in Block 12 wearing pajama pants and a hoodie, my front door having closed behind me with a soft click that felt way too casual for what had just happened. The hallway stretched ahead in sterile white light, and Martinez and four other guards lined the walls like mannequins waiting for someone to pose them. They all wore the same smile, too wide and too perfect, their eyes tracking me in perfect unison like some creepy synchronized swimming routine.
Level 5 breach, and I hadn’t even finished my morning coffee.
Sarah had literally warped reality itself to drag me back to work, which was a new level of clingy even for this place.
I took a sip of coffee and tried to pretend this was fine.
“Welcome home, Warden Evans.”
The voices spoke together, five mouths forming one consciousness, and Sarah’s presence saturated the air like humidity before a storm. The shadows in the corners moved wrong, breathing and watching and making my skin crawl in that specific way that meant something eldritch was having feelings.
Martinez’s smile stretched wider and his jaw cracked audibly.
I looked down at my coffee cup, still half full with steam rising in lazy curls. I’d been planning to drink this on my couch while watching trashy reality TV, which had been a good plan, a solid plan, a plan that did not involve interdimensional kidnapping at six in the morning.
“Sarah.”
My voice came out flat and dead tired, the kind of tired that goes bone deep and sets up a permanent residence in your soul.
The guards tilted their heads in sync and the movement was insectoid, deeply unnatural. Martinez’s neck bent at an angle that would’ve snapped a normal person’s spine, which was just great, exactly what I needed to see before breakfast.
“You came back.”
The chorus spoke with childlike wonder, relief and desperate joy that made my chest tight.
“I didn’t come back, you broke into my house and dragged me here through some kind of spatial horror tunnel.”
“Semantics.”
I started walking down the hallway, my slippers making soft shuffling sounds against the tile. The possessed guards watched me approach, their smiles never wavering and their eyes never blinking, which was definitely going to give me nightmares later.
Martinez was first in line.
I walked past him and the effect was instant, his smile collapsing as his eyes rolled back and the presence inside him snapped like a cut wire. He crumpled to the floor in a boneless heap, breathing steady but unconscious.
My immunity acted like an eraser, just deleting Sarah’s power from existence the moment I got close enough.
The next guard dropped as I passed, then the next, bodies hitting the floor in a rhythmic pattern that would’ve been funny if this wasn’t technically the worst containment breach in facility history. I kept walking and kept drinking my coffee, mostly annoyed about it getting cold.
The hallway ended at Sarah’s cell and the door was open, darkness spilling out like liquid while shadows crawled across the walls. They formed shapes, hands and faces and things that had too many angles to exist in normal geometry.
“You left.”
Sarah’s voice came from everywhere and nowhere, echoing off the walls and resonating in my teeth. The hurt in her tone was palpable and raw, like a kid whose parent forgot to pick them up from school.
I stopped at the threshold and looked into the dark.
“I was on mandatory leave.”
“You were gone.”
“For seven days.”
“Seven eternities.”
A shape coalesced in the shadows, Sarah’s human form emerging from the dark. She looked like the grad student today, brown hair in a messy bun with glasses and a cardigan over a band shirt, an appearance designed to look harmless and approachable. The shadows behind her writhed with barely contained power, which kind of ruined the whole gentle scholar vibe.
Her eyes were the giveaway, black from edge to edge with infinite depth. Looking into them was like staring into the void between stars, and I’d learned not to do that for more than a few seconds.
“I couldn’t feel you.”
She took a step forward and the shadows moved with her like a living cloak.
“The house was empty and your presence was gone, the fear in the city tastes wrong without you here. Everything tastes wrong.”
I took another sip of coffee, really wishing I’d added more sugar because the bitterness matched my mood perfectly.
“So you warped space to kidnap me.”
“I brought you home.”
“This isn’t my home, Sarah. My home has a couch and a TV and a door that leads to normal places like grocery stores and gas stations.”
She looked down and her hands twisted together, the gesture so human it almost hurt. Behind her the shadows pulsed, reaching toward me with desperate hunger.
“You were supposed to praise me.”
I blinked, genuinely confused.
“Praise you.”
“I fixed it, I made it so you could come back without driving. You don’t have to be far away anymore. Your door goes here now, it’s better, it’s perfect.”
She looked up at me with an expression so earnest and proud, like a dog that had just brought home a dead bird and expected treats.
I rubbed my face with my free hand.
“Sarah, you can’t just rewrite reality because you’re lonely.”
“Why not?”
“Because it’s a Level 5 breach, because you possessed five guards, because the alarms are screaming and the tactical teams are probably suiting up right now.”
“They can’t stop me.”
“I know they can’t, that’s not the point.”
I stepped into the cell and the shadows recoiled from me instantly, retreating like oil from soap. My immunity carved a bubble of normal space around me and Sarah flinched but held her ground.
“You made a mess.”
“I brought you home.”
“You scared people, you broke rules, you used your powers outside containment parameters.”
Her face crumpled and the shadows behind her shuddered, and for a moment the grad student facade flickered. I caught a glimpse of what lived underneath, something vast that existed in the spaces between dimensions, something that could swallow cities if it wanted.
Then she was just Sarah again, small and sad and looking at me like I’d kicked her.
“I just wanted you back.”
My chest did that annoying thing where it got tight, where empathy tried to worm its way past my professional detachment. I crushed that feeling down hard because Sarah didn’t need my pity, she needed boundaries.
I walked deeper into the cell and the shadows parted around me, hissing and whispering and reaching but unable to touch.
“Back in the cell.”
“But—”
“Now.”
I used the voice, the one I reserved for code reds, the one that meant negotiation time was over. Sarah’s shoulders slumped and the shadows pulled back, retreating toward the far wall while she followed them reluctantly, dragging her feet like a kid being sent to their room.
I kept walking forward and my immunity pushed against her presence, like walking through chest-deep water. Pressure built against my skin and the temperature dropped, my breath misting in the air.
The shadows tried one last surge, lunging at me from three sides in a desperation move. They hit my immunity field and dissolved like smoke.
Sarah made a small wounded sound.
“Please don’t be mad.”
“I’m not mad.”
I reached the far wall where the shadows had condensed into a tight mass, Sarah standing in the center with her human form barely holding together. The edges blurred and I could see the void beneath the skin.
“I’m disappointed.”
That landed harder than anger would have. Her face twisted and she wrapped her arms around herself, the grad student appearance flickering again. For a second she looked younger, smaller, terrified of abandonment.
“I just, I needed, you were gone and I couldn’t, the hunger gets worse when you’re not here.”
I set my coffee cup on the floor because I needed both hands for this. I reached out slowly, telegraphing the movement while Sarah watched my hand like it was a lifeline.
I placed my palm against the shadow mass, and the contact point glowed faintly, my immunity eating away at her power. She gasped but didn’t pull back.
“Back in the cell, all the way in. No more shadow hallways, no more possessed guards, no more reality warping.”
“You’ll leave again.”
“I’m on mandatory leave for four more hours, then I’ll come back. That’s how time off works.”
“Four eternities.”
“Four hours.”
I pushed gently, and my presence acted like a physical force against her power, the shadows compressing and retreating inch by inch. Sarah moved with them, back toward the reinforced walls and back toward containment.
“You’ll forget about me.”
“I literally came to work in my pajamas because you kidnapped me, so no, I don’t think I’m forgetting you anytime soon.”
A ghost of a smile flickered across her face but it died quickly.
“Promise.”
“Promise what?”
“Promise you’ll come back, promise you won’t leave forever, promise I’ll see you again.”
We’d reached the cell boundary, and the shadows pressed against the walls with nowhere left to retreat. Sarah looked at me with those infinite black eyes, and the void stared out, hungry and desperate and achingly lonely.
I should’ve said no, should’ve walked away, and maintained professional distance. But Sarah was shaking and the shadows trembled, and she looked like she might shatter if I didn’t give her something to hold onto.
I held out my hand with my pinky extended.
She stared at it like I’d just offered her the moon.
“What is this?”
“Pinky promise, it’s binding. More binding than your reality warps, more binding than contracts. It’s a human thing.”
“I don’t understand.”
“You loop your pinky with mine, then we make the promise. Once it’s made, you can’t break it, and neither can I. It’s a vow.”
Her hand materialized from the shadows, solid and real, and she hooked her pinky around mine. The contact point burned cold while my immunity flared and her power pushed back, the two forces meeting in the middle.
“I promise I will come back next week, same day, same time. We’ll have our regular session, but only if you stay in this cell. Only if you never escape again, only if you let the guards go and fix my front door.”
The shadows pulsed once, twice, and Sarah’s grip on my pinky tightened.
“And if you break the promise?”
“I won’t, I can’t. That’s how pinky promises work. But if you break containment again before then I don’t come back, the promise is void. You’ll go on the restricted list and I won’t be your warden anymore.”
Her eyes went wide and panic flashed across her face.
“No, no I, I’ll stay. I promise I’ll stay, I won’t leave, I won’t touch the guards, I’ll be good. I’ll be so good.”
“Then we have a deal.”
The moment the words left my mouth something shifted, the air crystallizing as a pressure wave rolled through the cell. The pinky promise locked into place and I felt it settle into my bones, a binding vow that was unbreakable. Sarah felt it too and her eyes flashed with recognition.
“It’s real.”
“It’s real.”
She smiled, actually smiled, and the expression was small and fragile and completely genuine.
“One week.”
“One week.”
I pulled my pinky back, and the contact broke. Sarah stumbled backward into the shadows. They caught her and cradled her while she sank into the darkness like it was a bed, the void wrapping around her protectively.
Her eyes started to close.
“Thank you.”
The words were barely a whisper.
I backed toward the cell door, and the shadows stayed put, not following. Sarah’s breathing evened out as the grad student appearance melted away, becoming something formless that existed between states. The hunger in the cell dimmed, not gone but sated enough, calm enough.
I reached the threshold and grabbed the door handle.
“Sleep well, Sarah.”
No response because she was already under, dormant, the shadows gone still. The danger had passed for now.
I pulled the door closed and the locks engaged automatically, seventeen mechanisms all clicking into place. The red light above the frame turned green and containment was restored.
I leaned my forehead against the cold metal, my hands shaking as the adrenaline caught up. The weight of what just happened settled on my shoulders like a physical thing, because I’d just made an unbreakable promise to an eldritch horror because she was lonely.
This was definitely going in my therapy notes.
I looked down the hallway where the guards were still unconscious, Martinez starting to stir. He groaned and his hand went to his head, confusion and disorientation written all over his face but probably no memory of the possession. Sarah had been weirdly gentle with them, all things considered.
My coffee cup sat on the floor inside Sarah’s cell, visible through the observation window.
It was probably cold by now anyway.
I turned and started walking back toward the entrance, my slippers shuffling against the tile. The alarms had finally stopped and someone must have hit the emergency override, the silence felt heavy and oppressive.
My front door was going to lead home again because Sarah had promised, and the vow was binding. She’d fix it, she’d behave, she’d stay contained.
For one whole week.
Then I’d be back here, same time, same place, because I’d promised too.
I really needed to renegotiate my contract.
