We watched "Inca Mummy Girl" tonight. Not the show's most creative title, or concept for that matter: What if we mashed up "Teacher's Pet" and "The Pack" but made it South American this time??
Gotta say, one of the hardest things for me on a rewatch, 20+ years on and knowing what we now know about Joss, is how gross so much of Xander's behavior is. He frequently acts super possessive with Buffy, and when the girl he likes in this episode tells him through tears that she doesn't deserve him, he doesn't tell her how wrong she is; it actually seems to make him happy to hear her say that. Ick.
