She used to be a very kind and gentle teacher, who speaks in a sweet voice. However, after The Hour of Joy, she starts to descend into madness. She slowly became murderously insane, forming a weapon from paranoia and calling it Barb, even considering it as a living person later on. She used to be SO hungry after being locked in the school for so long that she started to cannibalize on the rest of the teachers/her sisters. She used to teach anatomy for the School she was trapped in.
