I think there is a story there. Because Sinister didn't just manipulate the Summers family but also Katherine's. He was trying to make the perfect mutant. And I feel there is a story to be told there between the Greys, the Summers, Cykes moms family and Jeans moms family. I also feel like why would D'Ken choose a human female as a concubine? She must have been really special. He must have been trying to create a powerful heir. This stuff writes itself.
