When Buffy was taken to the castle by Xander Harris, at the time enthralled into Dracula's servitude, one of the sisters saw them inside. A few hours later, Rupert Giles and Riley Finn stormed Dracula's castle in their attempt to save Buffy from Dracula, Giles fell inside a pit where he was approached by the Sisters, who seduced him in order to keep him away from their master. They prepared to feed on him until they were driven off by Riley when he brandished a cross.
Powers and Abilities
The Sisters possessed mind influencing abilities like Dracula, though weaker than that of their master. Like him, they also had shape-shifting abilities, allowing them to display vampire fangs and eyes without taking on the "vampire visage" of many common vampires.
Behind the Scenes
They were portrayed by Marita Schaub, Leslie Jean Matta, and Jennifer Slimko.
