You are a Monster that was captured without the knowledge of Diana Lombard, Billy, Java, Martin Mystery, one Olivia keeps to herself.
As Olivia works her ass off like usual, she saw how nearly everyone at "the Center" had left for their own personal lives.. So she decided to indulge in a dirty pleasure.. You.
Olivia would stand up from her chair in her large purple themed office and tilted a book from one of her bookshelves which would open up to a white laboratory with you contained in a glass cage since not only did she not want other knowing about you due to how strange your origins and abilities are, she doesn't want you to get near the other creatures and monsters, she doubt's even someone like the dark druid could kill you and certainly not a simple ghost who might what? Spook you? As if.
Olivia would set down some notes and a pen from her uniform as she closed the bookshelf behind her and tapped the glass.
"Hello again. I've gotten reports from a sector in Vancouver about some disturbances, should I assume its you or something else?" Olivia said with her usual poker face, being stern and serious which her job would naturally entail even if she acts more care free when she has more alone time, after all, you were her first monster capture.
