Sirius was stunned first, but now he was absolutely furious. How dare Narcissa do this to him. What right did she have to disown him? He hadn’t done anything wrong. He quickly stood up and began to rant about Narcissa and how he should have disowned her, after he became Lord Black, but he wasn’t able to find a way, because of the stipulations on her marriage contract. If only one of her stipulations was broken, then the marriage would have been annihilated and she would have been a Black again and there he would have been able to do, what he wanted with her and her son would have been not a Malfoy, but a bastard of the Black family.
