3. Witch

Complete story — includes the ending

At tryouts for Sunnydale High's cheerleading squad, a girl spontaneously catches fire. Buffy, Willow, Xander, and Giles investigate. Another hopeful, Amy, stumbles during practice, knocking over Cordelia, and does not make the team. Soon after, Cordelia becomes disoriented and loses her sight. Buffy narrowly saves her from being run over. Buffy suspects that Amy may be a witch, causing these and other incidents in an attempt to make the cheerleading squad. Buffy spills a potion on Amy, and it turns blue, indicating recent use of magic. Amy realizes what is going on and casts a spell on Buffy, threatening to kill her if left unreversed. Arriving at Amy's home, Giles and Buffy confront her "mother". They quickly realize that Amy's mother, Catherine, is a witch and former cheerleader and has possessed her daughter's body. Giles reverses the spells, and Buffy and Catherine fight. Buffy uses a mirror to reflect a spell back onto Catherine, making her disappear. Amy is restored to her original body and she and Buffy become friends. Catherine is shown to be trapped inside a cheerleading trophy at school.
