Are two Xanders really better than one? We find out when a demon searching for the Slayer accidentally hits Xander with his weapon, splitting him in two; one with all the positive aspects of his personality, the other with all the negative. While each of them try to convince the Scooby Gang that the other is a demon, Buffy must find the real demon to put the Xanders back together.
