Doctor Andrelina Hastoff was a scientist.
She worked at Blueberry House, where she was in charge of rehabilitating robots suffering from "severe programming deviancy". When some of them achieved sentience, she thought it was a computer virus and was going to reset them to "normal". They broke out of confinement and captured Hastoff. They did not kill her, however, showing mercy as the Eighth Doctor hoped they would. (COMIC: The Autonomy Bug)
