Evil, Pure

Mr. E. Jones, being the brother of Mr. M. Jones (Bedbug), is evil incarnate. He is known as "Pure Evil" because when he comes into the common room, everyone feels guilty for not working, and therefore his mere presence is enough to bring fear of failing A-levels to everyone that is trying to enjoy themselves during a free period. He is also known as "Hitler", due to his tendencies to wear a small moustache and invade Poland (I think).
