Jean (The Curse of Fenric)
From Tardis Wiki, the free Doctor Who reference
Jean, along with her sister Phyllis, was an evacuee along who lived with Miss Hardaker. On a Sunday in April 1943 she met Ace and they went to Maiden's Bay. She later got in trouble with Miss Hardaker for going there. Jean and Phyllis later went back to Maiden's Bay and were converted into Vampires to serve Fenric. She and Phyllis returned to Miss Hardaker's cottage and drained her of blood, killing her in the process. She later marched with the Haemovores. She was killed when Fenric asked the Ancient One to kill all the remaining Haemovores. (DW: The Curse of Fenric)
