The last curse on our Thrice damned Atreides happens, for better reasons than the others, I think. The story of Chrysippus who was either one of few happy relationships we get to hear about, or the usual rape, kidnap stuff. And the discussion of whether or not Agamemnon is Atreus or Pleisthenes son. If Pleisthenes Exists. Also the Sun does a neat thing.
Reason we are explicit: Rape, Kidnapping, Murder, Incompetent Murder, Child Stew (original recipe), Adultery, Incest, and Existential Angst
