Biography
Toby was the son of physicist Sir Rupert Silverman. When he was young he used to be visited by a grey faceless entity, which his father would dismiss as a dream. Despite pleading to him, he still did not let him change rooms.

One day, Toby went with Professor Rivers to investigate the haunted Ashen Hill manor, where he met Sarah Jane Smith, Clyde Langer and Rani Chandra. He witnessed paranormal activity and Professor Rivers going missing. He later had a confrontation with Sarah Jane about ghosts as his father, a member of the science community, did not believe in the paranormal. Eventually he accepts the strange goings on to be alien activity. (TV: The Eternity Trap)
