If you're not Gryffindor, we'll disinherit you," said Ron…

““If you're not Gryffindor, we'll disinherit you," said Ron, "but no pressure." "Ron!" Lily and Hugo laughed, but Albus and Rose looked solemn. "He doesn't mean it," said Hermione and Ginny, but Ron was no longer paying attention. Catching Harry's eye, he nodded covertly to a point of some fifty yards away. The steam had thinned for a moment, and three people stood in sharp relief against the shifting mist. "Look who it is" Draco Malfoy was standing there with his wife and son, a dark coat buttoned up to his throat. His hair was receding somewhat, with emphasised the pointed chin. The new boy resembled Draco as much as Albus resembled Harry. Draco caught sight of Harry, Ron, Hermione, Ginny staring at him, nodded curtly and turned away again. "So that's little Scorpius" said Ron under his breath. "Make sure you beat him in every test, Rosie. Thank God you inherited your mother's brains." "Ron for heaven's sake," said Hermione, half-stern, half-amused. "Don't try to turn them against each other before they've even started school!" "You're right, sorry" said Ron, but unable to help himself, he added, "don't get too friendly with him, though Rosie. Granddad Weasley would never forgive you if you married a pure-blood." "Hey!””
