"I'm not–" Scorpius stopped himself. He would be lying if he said he wasn't hiding Hugo. That's exactly what he did when he told his father he wasn't gay or remotely interested in Hugo Weasley.
"They'll disown me. I'll be dead to them. If they leave me, I have no one. I don't have brothers or sisters or cousins. I probably wouldn't even have my godmother or godsister. If I tell them, that's it. I'll be alone." Anger and bitterness laced his voice. "You? You'll always have Rose and Albus and the rest of them. You'll have them long after I'm gone and you're seeing other blokes. I know it's not all right but I have to think about the long-term. Unlike you, I have to think about having children for my parents so when they get old they can rest knowing I didn't kill the name. I have to think about my duty to them above what I want."
Because this? It couldn't possibly last forever. Scorpius was a Malfoy no matter how much of a disappointment he was to the name. He wouldn't let go of his family. He couldn't. They would have to let go of him first.
