MONOMANIAC || Criminal Minds

Y/N is a major unsub that the BAU is putting all of their effort toward finding and taking down. Of course, these talented agents always work their hardest to take down an unsub, but this one? She's different.

Having been stalking the Behavioral Analysis Unit for an indistinguishable amount of time, Y/N has continuously succeeded in leading the team of agents on a wild goose chase. They have no idea what she may look like, what her life is like.

Usually they'd be able to figure that out easily enough, it was a huge part of what they do for a living. So why is it so painfully difficult for them to crack the code?

The answer is, in theory, very simple.

Y/N is not from their universe.
