The harsh fluorescent lighting of the mobile medical trailer buzzed with an irritating, uneven hum. Maya sat on the edge of a steel examination table, a thermal blanket draped over her shivering shoulders. Across from her, Dr. Travis Taylor looked as though he hadn’t slept in the seven days she had been missing. His eyes were bloodshot, his face pale and drawn, and his hands trembled slightly as he slid a sealed plastic evidence bag across the metal table.

Inside the bag was her olive-drab notebook.

“I’ve read it cover to cover, Maya,” Travis said, his voice raspy, devoid of its usual energetic cadence. “All forty-two days of entries. And Erik ran a biometric and forensic analysis on the ink, the paper, and the blood on the cover.”

Maya stared at the bag, feeling a sickening knot tighten in her stomach. “And?”

“The blood is yours. The handwriting is yours. The chemical breakdown of the sweat and oils pressed into the pages belongs to you,” Travis said, leaning forward, resting his elbows on his knees. “But according to your watch, and your own subjective memory, you were in that tunnel for exactly thirty minutes.”

“Because I was, Travis,” Maya insisted, her voice tight. “I walked in, found the brass casing, found the notes, hit the dead-end, and ran back out. That’s it.”

Travis rubbed his temples, a gesture of profound exhaustion. “In astrophysics, we deal with the concept of spacetime curvature. Down there, whatever that threshold is, it’s not just bending space. It’s fracturing time. I have two working hypotheses for how this notebook exists, and neither of them ends well for us.”

Maya pulled the thermal blanket tighter. “Tell me.”

“Hypothesis one,” Travis said, holding up a finger. “A localized temporal loop with neurological degradation. You actually did spend forty-two days in that cave. You survived, you hallucinated, you drank the water, you went mad, and you wrote those notes. But the anomaly’s localized EMF field acts like a magnetic wipe on the human hippocampus. Every time you reached a certain threshold of the cave, your short-term memory was violently reset. You wandered in circles for seven Earth days, experiencing a subjective month and a half, constantly dropping notes for a ‘past’ version of yourself, only to forget you wrote them minutes later. The thirty minutes you remember is just the final loop before you managed to stumble out.”

Maya’s breath caught. The idea of her own mind being hijacked, her body wandering the dark in a state of perpetual, amnesiac terror, made her skin crawl. “You said there were two hypotheses.”

“Hypothesis two,” Travis continued, his tone dropping an octave. “Quantum superposition. Many-worlds theory. The threshold isn’t a door; it’s a prism. When you crossed over the second time, you didn’t just walk into the dark. You shattered into multiple probable realities. The tunnel you walked down was an intersection. Those notes? They aren’t from your future. They are from the Maya who turned left when you turned right. The Maya who got trapped. You experienced thirty minutes, but you were walking through the debris of other dimensions where your parallel selves were suffering for weeks.”

Maya stared at the blood-stained notebook. It’s wearing her face. I had to shoot. Vance’s carved warning echoed in her skull.

“Where are they, Travis?” Maya asked suddenly, a cold dread washing over her. “Elias, Jax, Vance. You said I was gone for seven days. Where is my team?”

Travis’s expression hardened. He looked away, staring at the blank metal wall of the trailer.

“They didn’t go back in with you,” Travis said quietly. “But the cave didn’t let them go.”

He pulled a tablet from his lab coat and tapped the screen, turning it toward her. It showed a heavily quarantined medical room. Elias lay in a hospital bed, hooked to half a dozen machines.

“Elias is suffering from rapid cellular senescence,” Travis explained grimly. “When he came out, he said he’d been walking for four days. His body believes it’s been decades. His telomeres are degrading at an impossible rate. His organs are failing. He’s aging to death in front of our eyes, Maya. And when he’s conscious, all he does is scream about the geometry of the ceiling.”

Maya covered her mouth, her eyes watering. “And Jax?”

Travis swiped to the next file. “Jax is in a medically induced coma at a classified black site in Nevada. The nosebleed he had when he came out… it didn’t stop. But that’s not the worst part. The blood leaving his body refused to adhere to standard Earth gravity. It pooled on the ceiling of the medbay in perfect hexagonal patterns. We had to sedate him just to stop his heart rate from pumping more of the anomaly into our atmosphere.”

“Vance,” Maya choked out. “What happened to Vance?”

Travis lowered the tablet. He looked directly into Maya’s eyes, and for the first time, she saw true fear in the scientist’s gaze.

“Vance is in a padded containment cell fifty yards from here,” Travis whispered. “He’s completely lost his mind. He hasn’t slept in seven days. He just keeps repeating the exact same phrase, over and over, begging us to give him his rifle back.”

“What phrase?” Maya asked, though her blood was already turning to ice.

“He keeps saying, ‘She didn’t bleed when I shot her. I have to finish the job.’“

Maya went entirely still. Slowly, mechanically, she reached her right hand up beneath the thermal blanket. She pressed her fingers against the fabric of her tactical shirt, right over her left collarbone. Her breath hitched.

Beneath the fabric, her skin was perfectly smooth. But buried deep underneath the muscle, she could feel the distinct, hard, cylindrical shape of an embedded 5.56 caliber bullet.

She hadn’t bled. And she didn’t remember getting shot.
