"The notorious escape artist patient, a master in cryptography and stealing things that aren't hers. Caroline lurks around the hospital deceiving staff and plotting escapes from this prison- sure, none of her attempts to escape have worked, but she keeps trying! Caroline is known for their bad habits and their many... partners."

Similar juvenile humor as Uni, often rude in other ways as well.
