From TARDIS Index File, 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 later marched with the
Haemovores. She was killed when Fenric asked the
Ancient One to kill all the remaining Haemovores. (
