"Dad, there will be an heir. The how and why are my business and it will stay that way," he answered, rather cooly. "If I hadn't want to, I wouldn't have been so careful. After all, if it weren't for this, you would have never found out and no one else would have told you, because no one knows. Only Azriel and Charlotte used to know. That's it."
Stephen snorted. "Of course that's a reason. His father would have killed him, and I mean that literally, and I knew I would have to get married and have a child. There was no reason to stay together. This was when we were in school. We've avoided each other for years. He mostly went out of the country. I went Muggle. We met by chance a few months ago, and then he had to work, moved to Hogwarts. Then this happen. So we've been together for years or months, depending on how you want to see it."
