Marianne was a rather young member of squad 12. They were an adult, they were just on the younger side.

Marianne was rather intelligent and a bit odd, so they fit in well in the squad.

One day, while Marianne was in the lab, clicking away at the keyboard, working, as Mayuri approached them.

Mayuri looked at them.

"You're young."

He stated, his expression looking neteral but having a hint of seriousness. He was stating the truth.

"Explain to me what 'FNAF' is."

Mayuri asks, completely seriously.
