Slavoj Zizek voice: "to an outside observer the sexual fantasy of the 'step-brother' or 'step-mother' is just the latest form of incest, but if you look at it from a different angle, you see it is in fact a desire for the freedom from the labor of finding a partner, sublimated into having your parents finding you an outlet for your desire with no effort on your behalf. It is a form of incest that surpasses Oedipus, absolving him of the responsibility for his actions."
