Toby Silverman
From Tardis Wiki, the free Doctor Who reference
Toby Silverman was the assistant of Professor Rivers. He went with her to investigate a haunted 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.
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)
