I enjoy this ep, I think it has some extremely funny moments-- but it also has some very boring moments, and the whole premise of it is kind of poorly developed. Xander's been a Scoobie for over two years at this point, and all of a sudden (based, so far as I can tell, entirely on the fight at the beginning of the episode) he's too weak and (to borrow a pharse) kitteny to fight with them? All of a sudden they want to protect him from everything he's seen over the last couple of years? That's sort of silly. It's true that he needed validation of his role within the Scoobies, but the others had never voiced such concerns before this ep.
