Katie Russell
From Tardis Wiki, the free Doctor Who reference
Katie Russell was Owen Harper's fiancée before he joined Torchwood 3. She was believed to suffer from Alzheimer's disease, which would make her the youngest case ever. Owen did not trust this and ordered examination after examination, even though none showed up anything unusual. Eventualy after a last a brain scan the doctors thought that she had a brain tumor. During the operation it turned out that she was infected by an alien creature, which in self defence killed both the doctors as Katie herself, to the devastation of dr. Harper. (TW Fragments)
