The Red Room | Aaron Hotchner · Y/n story by @ppips

The explosion swallows the silence whole. For a moment, there is nothing but ringing static—the world reduced to sound and dust. Chunks of concrete and twisted rebar skitter across the tarmac, bouncing off helmets and vests. The doorway gapes open, a black wound in the concrete, its edges glowing faintly orange.

voice low, clipped Reid. Eyes up.

Reid steps through last, tablet in hand, flashlight cutting a sharp white beam into the corridor ahead. The walls are bare. No posters, no signage, no scuff marks. The floor is clean enough to reflect the glow of his flashlight. It looks less like a building and more like a machine—every surface designed for a purpose, nothing left to chance.

lowering his weapon a fraction This isn't a training facility.

quietly It's a vault.

A sound echoes from deeper inside the facility. It's not footsteps. Not voices. It's something mechanical—a low hum, rhythmic, like a heartbeat made of metal. It's coming from the far end of the corridor, where a second door stands half-open, spilling a thin strip of white light across the floor.

Reid

barely above a whisper That shouldn't be running.

Hotch

We move. Now.

The team advances down the corridor in tight formation, weapons trained ahead. The hum grows louder with each step, vibrating through the soles of their boots. The light from the half-open door steadies, flickers once, then holds.
