The professor calls Faith tells her that she has been lying to everyone, he points directly at Faith telling her that maybe he can’t do anything to her, but possibly another slayer can, at that, he gives Buffy something to punish her with. Buffy takes what the teacher gave her and knows what to do, Faith stands against the table, pulls down her pants and is ready for her punishment.
Buffy starts to spank her, telling Faith the reason for each of her blows, as she continues Faith’s buttocks get redder and redder, but Buffy doesn’t stop until she finally finishes the punishment.
But at that Faith tells the teacher that Buffy has been lying about Angel, so he tells her that she deserves punishment too, Buffy knowing she can’t deny it, takes off her skirt and Faith retaliates, she starts hitting her taking it out on her and leaving her buttocks as red and sore as hers.
After their punishment they both leave, accepting that it was a punishment and don’t bother each other.
