Nelson, I'm going to have to agree with Tami here on this, the ritual curse that wiped out the Red Court was keyed on the youngest member of a bloodline, which would carry it into the preceding generations to complete it's effect which is why they were targeting Maggie Jr to kill Harry and Ebenezar. But with Ramps it's not so much of a genealogical bloodline as it is a metaphysical one based on how they turn victims into the half breeds like Susan and Martin...the curse worked to wipe out the Reds because at that moment Susan was the youngest in the Red Kings bloodline, and through him it would annihilate the rest. Maggie Jr if anything has a better chance at being a wizard due to her parentage than to have any aspects of the Ramps predator spirit inside her.
