Betty Yeadon
From Tardis Wiki, the free Doctor Who reference
Betty Yeadon, previously Betty Harper, was an inhabitant of the village of Crook Marsham.
She blamed herself for the death of her brother Alfred, since she encouraged him to enlist. When the Sentience manifested in 1968, it appeared to her as Alf so it could use her guilt to let it feed on and kill her. (PROSE: Nightshade)
