A son was pushing it in his mind, he feared the thought of raising a child. He would be a terrible father, but then he didn't have much of display to go off of. He was too emotionless to give anything to a child, and he doubted he could love a child when the love he had was for Bellatrix, Of course in a proper world at least having a weakness like a wife and child would not be such a problem.
"A daughter would be lovely with your looks, let us hope she does not get to many of mine," Rodolphus gave that throaty sound of a laugh. "I do say she would bring in proper suitors, we would make sure of that. Just as we would make sure our son found a proper woman." Rodolphus had never thought of having a daughter, the idea of one child was enough to make him worry.
