I am rereading Blameless, and I noticed that Mr. Lange-Wilsdorf assumes that Alexia will not be able to carry to term based on the lack of success of the Templars' breeding program. Why do you think Alexia was able to conceive and carry Rue to term as opposed to the female preternaturals the Templars presumably tried to breed with mortals? Is it because preternaturals cannot share the same space with other?
