Theobald

Theobald, also derisively called Tibbald by Alexander Pope, was a companion of the Ninth Doctor, who travelled alongside Alexander Pope. Tired of the constant arguing between the Theobald and Pope, the Doctor threatened them with restriction from the TARDIS food machine's supply of viennetta. (PROSE: Double Falsehood)
