OK, let's give Kubo the benefit of the doubt here. I know it's a very generous gift, but let's give it all the same.

Let's assume he still remembers that he classified Masaki as a human. Now, let's think about Ichigo's powers. Even though he was the son of a Shinigami, his powers didn't activate until Rukia transferred her power into him.

Now, let's apply that same logic to Masaki. What if she were the daughter (or perhaps granddaughter) of a Quincy who had married a human? It could be that she always had the potential to be a Quincy, but the Quincy lineage had been diluted by a human's. Thus, they lay dormant in her. She might've required an outside source to jump-start her powers, like Ichigo, and it never happened. And when Ichigo was born, he received some of the Quincy's lineage in his bloodstream too. Not enough to make him a full-blown Quincy, but enough to contribute to his spiritual awareness and power, and later activate when he absorbed Quilgy's reiatsu. It would also explain why Isshin married her; he might've sensed her unusual lineage.

Of course, it's just a theory, but if Kubo is actually trying to come up with a logical explanation for Juhabach's insinuations, this would be my guess. Anyone else have any theories?
