Severus snorted and ignored her.

"You are going to share all this information with me eventually if I am to protect the you know what, the little darlings." Flan told him.

The more she knew about Scarlet and her life, the easier it would be to slip into protector role.

"They are close." Severus responded gruffly. He shut his mouth immediately after that, unwilling to divulge any information. She would have to pry it out of him some other way.

"Are there any complications in the relationship? Will I at some point have to talk to her about how to maintain a well balanced relationship for her sake and that of the children?" Flan asked him.

At some point, the human would surely notice that his children were special and had some unknown energy.
