Aaron Hotchner needs a smack upside the head, is the only thought that is crashing through your mind as you bound down the hallways of the warehouse. Your feet slap against the pavement, your heart rate increasing ten fold. The air feels thick with death and fear. Adrenaline pumps through your veins as you frantically scan for any hiding place.

For the last month, your team had been working on a jarring case. The unsub had managed to kill almost thirty people without being caught. Remains of sulfuric acid was found on the victims bodies. It was something you'd never seen before. The unsub was the perfect killer- straight out of a horror film.

Hotch got the brilliant idea of sending you to investigate an old dump site. You curse him as you run weave under fallen banisters, the soft sound of melodic footsteps behind you. A soft gasp leaves your lips. Quickly, you squat behind a fallen wood panel to gather your thoughts.

You had dropped your gun a ways back. He had caught you off guard- startling you.

The sound of your rapid heartbeat mixes with the echo of his heavy footsteps. Mind going into a frenzy to recount for what you'd seen. There was no way- the man after you was a legend in the unit. You couldn't believe Spencer Reid was here. There had to be an explanation.

"You can run, but you can't hide.." His voice rings out, panic rising in your chest.

When you see a doorway through the dim light, relief sets in. An exit sign glows with your right of freedom. you bound towards it, crashing into the impenetrable doors. you were able to pull the door open just enough for a breeze of night air to slip in, a large hand coming from behind to slam against the surface.

"You dropped something, sweetheart." He says, his voice rough.
