Toby Silverman

Toby Silverman was the assistant of Professor Rivers. He went with her 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.

He 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. (SJA: The Eternity Trap)
