"It would be best if you didn't introduce us as FBI," you told the social worker that drove with you to the ranch.

An anonymous 911 call had been made, claiming the leader of a religious cult was sexually assaulting young girls. You and Spencer had been assigned to look into it undercover.

"It would be even better if you didn't introduce her at all," Spencer muttered from the back seat. You glared at him.

Spencer and you had been working side by side at the BAU for years. You'd never gotten along though. Nobody could figure out why, really. You were both smart, young, driven. But you were also very competitive.

You tried to like Spencer at first. You really did. But he was always dismissive at best and hostile at worst. Eventually, you decided he was an insufferable showoff. He never wasted an opportunity to undermine you and show he thought he was smarter than you. You loathed it, mostly because you were just as smart as him. And you did everything you could to show it. You had a unique skill for pushing Spencer's buttons. And you did it every chance you could because you kinda loved it. You were determined to one day shut him up. He was not very fond of that.

You had both protested when Hotch had assigned this to you. There was no way you and Spencer got undercover together and without ending up handcuffing each other at some point. You thought you could do a better job on your own. Spencer would've rather taken Morgan, but that’s the way the cookie crumbles.

Nevertheless, you had a job to do. You were in the process of interviewing the last girl when the leader of the cult, Cyrus, and some of his men barged in, guns in their hands. “What do you know about a raid?!" He asked.

Nothing. You knew nothing at all.

Things only escalated from there. The social worker you'd come here with was dead. Cyrus was agitated. Dangerous. He'd barricaded everyone in, and before you knew it, you and Reid were being escorted into a room.

"We're officially hostages," you said, your tone bitter.

"You think?" he retorted.
