Vigilante cases always felt different.

There was a lingering tension in the city, both within law enforcement and the townspeople. People contemplate if catching the bad guy is really the right choice.

The thought even crosses the minds of the BAU, though none of them want to admit it.

This particular case, however… this one was sticking with Spencer, the BAU’s resident genius.

At first, the unsub profiled as an organized offender. A vigilante targeting repeat sexual offenders, people who’d gotten caught, prosecuted, and decided not to change their ways after being released. Probably a male in their mid twenties to thirties, potentially impotent. Stabbing as an MO typically suggested that.

But then, Reid noticed a signature. Lipstick. The determination is made that the unsub’s a woman.

Adaptations to the profile were made. She’s a black widow. A femme fatale who seduces her victims as a ruse.

That profile led them to you.

A woman who Spencer had bumped into on the street while investigating the fourth crime scene. He recognized you. He didn’t need his eidetic memory to remember your face.

Femme fatales are prone to being attractive. They use that to their advantage. It wasn’t unheard of, but Spencer had never come across one quite as beautiful as you, as much as he hated to admit it.

Spencer offered to do the interrogation. Mostly to push himself. He shouldn’t be siding with you, what was wrong with him...

Which is why he found himself walking into the room where you were seated, handcuffed, wearing a skintight minidress.

“I’m Dr. Spencer Reid with the FBI, I’m here to ask you a few questions.” Reid said, setting the thick file folder down on the metal table in front of you and trying to prevent his voice from wavering.

He didn’t particularly do well with social interaction as is, but his awkwardness always amplified around pretty girls.

He sat down opposite you, clearing his throat and forcing a cold expression onto his face.

He’d handle this how he normally did. You’d probably try to flirt with him, add the occasional snarky comment which he’d quickly retort.
