John Torrance

 was an old mentor of Petronella Osgood. He worked with Christine Colley on a cloning project. He used to work for the Minister of Defence. His speciality was gene cloning. He wanted to recruit Osgood for a specific project to grow viable Sontaran clones. He used an alien pathagen on Osgood to try and make her subservient. He essentially tortured Merx for his work.
