This tied together and explained fragmented flashbacks that had suggested Zor-El was a villainous character, including his dismissal of schoolchildren taunting Kara as "the dead" (they had already been possessed) and Alura telling Kara to kill her and "make your father proud" (she had also been possessed, and this was not a taunt but a genuine request from what remained of her original personality) as well as the original idea that he wanted Kara to kill Kal-El. As the story ended, it was revealed that the house of El was cursed by the phantoms as they saw them as their jailers. Wherever one of the El blood line went, the Phantoms would follow. To save Earth, he needed to send Kara to remove Kal and stop the El blood line from ever-growing.
