Walter Simeon

Dr. Walter Simeon was a man associated with the Great Intelligence.

Biography
Walter Simeon found the Great Intelligence as a young boy, and unwittingly began pouring his darkest thoughts into it. Believing its orders to be its own rather than a reflection of himself, Simeon began to go about building an army of ice for himself to be in power. To this end he established the Great Intelligence Institute and sought to bring the Ice Governess to the Intelligence, which brought him up against the Doctor.

When he confronted him at the Institute, the Doctor showed him how the Intelligence was nothing more than a reflection of Simeon himself rather than a separate entity. Undaunted by this revelation, Simeon sought to get the remains of the Governess, but the Doctor tricked him into being bitten by a memory worm. The memories of his adult life were erased, but the Intelligence had by this time gained enough independence to survive and fill in the void left and take over Simeon's body. After a brief scuttle with the Doctor, whatever was left of Simeon died when the Intelligence was defeated and relinquished control of his body. (TV: The Snowmen)

Personality
Walter Simeon was a cold hearted sociopath. As a child he believed that other children were "silly" and didn't want to play with them. His mother commented that his solitary nature was unhealthy and since Simeon never even tried to emotionally connect with other people he grew into a heartless man who showed very little emotion. He allowed his Snowmen to eat a group of homeless people who had been building them without any concern for their lives, coldly stating, "I said I'd feed you. I didn't say who to." An intelligent and very power hungry man, Simeon was determined to take over the world with his ice army, although for most of his life he thought he was obeying the orders of the Great Intelligence, not realising that it was a reflection of himself. The one time he did show emotion was when he realized who and what the Great Intelligence was, seeming shocked and slightly fearful of the entity he had served for his entire life.

Simeon was also shown to be arrogant and casually informed Vastra and Jenny Flint of his plan, believing that there was nothing they could do to stop it. When Vastra said she knew someone who could stop him, Simeon merely responded "I look forward to meeting him" not taking the Silurian's words seriously. He was also indifferent when he lifted Vastra's veil and saw she was a Silurian, and although he commented that the Veiled Detective was a woman, possibly implying a degree of sexism, he said nothing about her species.
