"Draco Malfoy, you show yourself right now!"
Draco had run into his father's study where there were "Do Not Disturb" charms placed on the room that could be activated to keep anyone out, including and especially his mother. Draco tried to get the wards up before Narcissa caught up with him but he had only activated the spell once, when he was fifteen, and his wand work was sloppy. Before he could get out the last few syllables Narcissa stormed into the study wearing an expression that let it be known that she would have liked nothing more in that instant than to curse her only son into oblivion.
Narcissa had invited her close friend Hilaire Molyneaux and her daughter Angeline to have lunch with the Malfoys, as she frequently did. Both mothers seemed hell-bent on forcing their children united in matrimony. Angeline, who by Pureblood standards was already too old to be unwed, was a huge fan of the idea. Draco was not.
"What. Did. I. Tell. You. Before. They. Arrived? I said that I would not have you insulting our guests, Draco Malfoy, and I meant it! How could you run out of lunch like that without even excusing yourself, the height of disrespect I tell you, it's like I raised you in a barn, absolutely no thought towards your father and I-"
"Mother, she grabbed my hand and forced it under her dress, and she wasn't wearing any knickers! Why do you insist that I marry this girl, she's a slag! I knew I should've gone to Blaise's ancestral home to hide out-"
"Oh don't be ridiculous, Draco." Lucius entered the room and stood behind his wife. "You've threatened to go to Africa more times than your mother and I can count, yet you chose to come to France. To Blaise's summer home, in the next town over from where your mother and I have been living for twelve years. Why not with Gregory Goyle, who has completely isolated himself from society somewhere in Canada? You purposely chose this location because you knew that we'd know your every move and you wanted to flaunt it in our faces that you have not been abiding by our wishes for you, and I agree with your mother. That is the height of disrespect, and I believe that you owe your mother and I an apology."
"I believe that you and Mother owe me an apology for thinking there's no one out there for me who is better than that girl."
"That girl is the best you can do! Don't you understand that? No Muggle-born or Half-blood will ever have you because you are a Malfoy, and only the most money-hungry Pureblood woman would take you, of which there is one left! Angeline is our only hope for continuing the Malfoy name, and-"
Whatever Lucius was going to say next was lost as all of the Malfoys' attentions had now been diverted to the tapestry on the far wall, which was glowing. The trio stepped forward in unison to take a closer look at what was happening. They all saw it almost at once. On the last extant branch of the Malfoy family tree, a bud was forming next to the branch labeled "Draco Malfoy." Next to that bud, golden thread spelled out the name "Hermione Granger."
Narcissa gasped and covered her mouth in shock. Draco stepped even closer to the tapestry, tracing the new addition with a look of utter confusion on his face. Lucius, whom Draco had never seen lose his composure in Draco's three decades of life, turned to his son in horror.
"What the fuck did you do?"
