Buffy: The High School Years - Parental Parasite (Buffy: The High School Years)

Buffy struggles to deal with her mom Joyce's newfound interest in spending time with her. Balancing that with her schoolwork, her friends, and her regular vampire-slaying duties is a challenge. However, when Joyce becomes hypnotized by a childlike demon that craves motherly care, Buffy experiences a new kind of sibling rivalry-except in Buffy's case, her 'sibling' is actually a monster!
