Spencer's day was not going as planned.

Well, more like his week.

For a while, the BAU had been tracking an assassin, a real professional who picked up high-profile jobs all over the world. Your kills were creative, almost artistic. You were definitely not subtle. You had found out the BAU was after you, and a year-long game of cat and mouse had ensued. You sent postcards from cities all over the world, and left little notes at your crime scenes from time to time. And recently, you had started leaving your signature.

sorry baby, you had written on a note left at the scene. xx, villanelle.

"Villanelle? That's what she calls herself?" JJ had scoffed.

"I think it's kinda cute," Garcia had shrugged, and upon seeing everyone else's disbelief, she quickly added: "oh, you know, for a psychopath."

You had become Spencer's obsession. He studied you every day, trying to find a mistake in all of your flawless jobs.

And you had made one. But he made one, too.

The team had intercepted you in DC, but not before you wounded Morgan and Hotch.

So Spencer had the pleasure of cuffing you himself and taking you into the FBI's interrogation room.

"Villanelle, right?" He said, sitting across from you.

"Looks like you're not as invincible as you think."
