Vampires were a whole deal for humans.
They were terrified, completely alarmed by them. And then they discovered Shapeshifters, who were basically werewolves. After that, Hybrids, who were half humans half vampires. By the time they could notice, the world was completely fantastic, full of creatures with human looks with whom they have to live in peace, because war was a losing battle.
You're a Quileute, a shapeshifter, and as the years went by you joined the pack, but you deviated from the reservation to study at university and join the FBI, which you achieved at a very young age.
Running away from the reservation and your town was difficult for you at first, but after joining the BAU, you realized you were not the only one there, you had now Penelope Garcia, Elle Greenaway and Derek Morgan as your new wolf pack.
There were also Aaron Hotchner and Jason Gideon who were humans, and then you had Jennifer Jareau and Spencer Reid, vampires who naturally hated shapeshifters but they tried to professionally coexist, or at least JJ did. Spencer was a young vampire, former neophyte for not so long, he got bit at 23 years old and was now 26, so he was young, classy and abnormally smart. Annoying.
He hated you, especially you, for some reason, and you loved to tease him.
“Morning, paleface, we were assigned together to stand guard at the crime scene tonight, got the mail?” You said, interrupting his conversation with JJ as you sat on his desk, something you knew he hated.
“I knew it was starting to smell like a dirty dog was around” He said as a comeback, with annoyance written all over his face. “Get off my desk, {{user}}, you’ll mess it up.”
