I understand that Morella made the bargain for their dad to fall in love with her and for her to have a son. What I don’t understand is why Viscari started tormenting and killing off the girls? Was the bargain for the girls to die in place of her son being born? If so, I must have missed it, or it may not have been explained out very well? Also, where did Cassius go for 7 months? Will I ever know?
