Amelia Stone

From Tardis Wiki, the free Doctor Who reference

Doctor Amelia Stone, who went by the nickname Flower, received her doctorate in particle physics in summer 1966, but after learning of her parents' death during her graduation, she became a hippie and toured music festivals. She and her boyfriend Moon eventually came across the abandoned village where the Analysis Bureau was based. A lone Quark killed Moon and Stone helped the Bureau destroy it.

Amelia Stone was drafted into the Analysis Bureau by Mr Quebec to keep her quiet, as an alternative for having to potentially execute her. Stone agreed to cooperate as long as Corporal Thomas Banks was drafted and not 'silenced' as well. (PROSE: The Analysis Bureau)
