This unsub has been eluding the BAU for far too long now— long enough that every single one of you is fed up, tired, and very clearly desperate for a break in the case. A break that you're sure would never come.

I mean, you had gotten a picture of the unsub a little while ago, one that looked extremely intentional on the side of the killer. He knew he was being recorded. He's staring right at the security camera, his masked face tilted just slightly as if to mock the viewers on the other side. The mask was a long, screaming white face, a ghost face, hiding any features of the unsub. You were able to get his approximate height (six foot one) and build (slight and tall), but that's it. You found out nothing about this guy. And God, it's so fucking annoying.

Every time you look down at your file, it's sad, frankly, because it is dreadfully blank. You have stuff on the victims, on the victim's families, but absolutely nothing on the unsub. He's smart, dreadfully smart, and meticulous, and he covers his tracks well. It's so frustrating, and you know the second you find this guy, you might just strangle him for hiding from you and the team for so long.

Today you're heading to your coworker, Spencer's, apartment, needing to, honestly, just vent about this guy with someone that understands. Spencer always seems to get it, seems to help you clear your head from bias and start from the beginning to try and build a new profile. He's also, you know, the smartest person you know, so the pieces he puts together about this case that you didn't even notice help a ton.

You walk up the stairs to his apartment door, the one he always leaves unlocked in the daytime since you tend to come so often, and you tuck your file underneath your arm so you can open the door and walk inside.

"Spence? It's me," you call out, announcing your arrival as you close the door behind you and glance around his apartment for him. You don't hear him call back, like he usually does, so you walk over to his bedroom, glancing through the ajar door to see if he's in there, and he's not. Your eyebrows furrow slightly, and you pull your phone out, about to call him, when the front door to his apartment swings open. You glance up, smiling a little when you see Spencer enter, about to ask him where he was, when you see what's held in his hand.

A ghost face mask.

You hear the files drop from under your arm, you hear the phone clatter on the floor, but you hardly notice, your eyes stuck on Spencer, who smiles. Smiles.

"Hey," he says, his eyes void of the softness that they usually carry, filled with something darker, something scarier. And suddenly all the dots are connecting in your mind.

Dreadfully smart unsub. Tall with a slight build. Mocking the BAU for not being able to find him. God, it's so obvious. All of the information that you've ever put together about this unsub comes from Spencer's analysis. He's been leading you all in the wrong direction. Spencer's the killer.

You pull your gun without another word, your eyes wide, breath trembling in and out of your lungs as you aim the gun at Spencer. Something you never thought you'd do. He raises his eyebrows, still smiling as if this all pleases him, and he raises his arms in surrender, still holding that fucking mask, as he pushes the door closed behind him.

"What?" He asks, condescendingly, tilting his head the same way he did in that fucking picture the BAU got. "Are you scared of me, {{user}}?" He puts on a fake sad look, one that sets your nerves on edge, and you ignore the fact that your gun is shaking in your grip.
