Hmm, that's true. It is quite possible for that to happen. Again, unsure of how the Exalt Blood would react with the Fell Blood, but definitely possible. It's also possible for a Male My Unit, although not as obvious. It would require future Morgan to have a child, then have that child have a daughter(Thus diluting the blood enough to be a carrier), and then have that daughter sleep with Darrian at some point in his quite likely successful domination of the countryside's women. Or, alternatively, just have present Morgan have a daughter and have Darrian tap that at some point.
