Confessional: The Doctor's Cut

The big names of horror have all been found, caught, and detained. A new program leader at Rockwell's Facility, built and made for criminals who could only plead insanity to there horrid crimes, decides that investigations of the serial killers are a need. In the right side of the building is where the world's worst nightmares rest and only one psychiatrist has been assigned all of them. She seems weak, scared, and not at all competent. Except, is she really scared? Or is she appealing to a serial killers ego? Little do the new slasher friends know, but she had a lot more to do with putting them in their cages than her outward appearance suggests.
A psychiatrist who loves the hunt. A women who knows how to bend her image to get what she wants. As the killers begin to find out that there is another monster roaming the halls, an incident involving the power and a forced reboot show the true strength of the wolf in sheep's clothing.
(Y/n) never expected to become their favorite of all things, but atleast this way, she gets all the information she needs. A plan is being formed, killers are forcing away their antisocial instincts to work together, and she is non the wiser.

Pairings (Platonic? Romantic? Who knows)
Reader & Michael Myers
Reader & Jason Voorhees (slightly more platonic)
Reader & Thomas Hewitt (Leatherface)
Reader & Hannibal
Reader & Billy Loomis
Reader & Stu Macher
Reader & The Collector
Reader & Harry Warden

In the end, there will be only one pair.

Warnings:
This is based on sadistic serial killers. Every warning that their movies possess should be used here. Preferably, people above the age of 13 should be the only ones reading. This is also, technically, a slow burn, mixed with the usual non-consentual kidnapping and other acts.
