When Harry arrives at the Burrow in "Harry Potter and the Goblet of Fire", Molly finds out about Fred and George's experimentation with dangerous sweets they were manufacturing and tells them off before leaving for the Quidditch World Cup; however, after the Dark Mark appears over the sky at the World Cup campsite, Molly is upset for yelling at Fred and George, worried that something might have happened to them after she treated them so horribly. Towards the climax of that book, Molly and Bill arrive at Hogwarts to see the Third Task of the Triwizard Tournament, acting as family guests to Harry. After the return of Voldemort, Dumbledore asks Molly and Bill to join the Order and fight in the impending Second War. Molly comforts Harry and, for the first time in his life, he has someone to be there for him, like a mother.
