"The Nott family has always been evil, Theo’s the first sane heir in all of recorded history." Pansy said, standing up to her full height, letting the extra few inches she had on Hermione be used to try and intimidate her. "Centuries ago, one of his ancestors was completely mad. He demanded a perfect heir, killing off ten of his children. His wife, after giving birth to their eleventh, sacrifices herself in a ritual that would safeguard the heir from being slaughtered by the head of house. Therefore, the only reason Theo lives, despite his father’s best efforts, is because he is the heir. Once Theo claims Athena as his heir, that protection will no longer apply to the both of them and Thoros won’t hesitate to kill his son. In fact, I wouldn’t be shocked if he’s been hopeful that Theo would have a child sooner rather than later so that he could kill him."
