Hannah Bennet
From Tardis Wiki, the free Doctor Who reference
Hannah Bennet was a pupil at St Cecilia's School for Girls. She informed George Litefoot about his predecessor. She was, according to Ravener, a troublesome pupil. In a lesson about the circulatory system, she informed him about some weird stuff. She was later used by Ravener as a bargaining chip. (AUDIO: School of Blood)
