Oliver

Oliver appears to be a troublemaking, sociopathic boy with a knack for fun, even going far as to kill people. He lacks a heart and appears to have more affiliations with the teachers, which may explain why they let him go free. Some speculate that the reason why he's a troublemaking person is because of his background as a traumatized and jealous person of Claire's "normal life." Oliver is rather violent and has little to no care for his own personal health, as well as having a habit of eating non-edible things, even some that are harmful to him, such as razor blades. Despite this, there is a theory that Oliver is actually trying to help Zip do her work, giving somewhat of a good personality.
