Eurus Holmes

Eurus is considered perhaps the most intelligent human being alive and is a master of manipulation. As a young child, she lacked emotion and seemingly the ability to distinguish her own pain, cutting open her arm because she wanted to see how her muscles worked. As an adult, she has slipped between being calm to screaming and, when finally seen, to being a helpless child alone on a malfunctioning air-plane. Eurus lacks typical normal human feeling, but she watches and reads the emotional reactions and emotional states of others, manipulating them to her favour in order to better understand an individual, or, for Eurus to feel something about what she's doing. A part of Eurus, however, is aware of the wrongdoing of her actions but, like the child helpless on the malfunctioning plane that she experiences herself to be, Eurus has no idea how to behave differently than how she already is, much less succeed or even progress in that area.

Eurus is not above killing a person. She actually enjoys it and loves to make it last..
