Molly Weasley (née Prewett) is the wife of Arthur Weasley and the matriarch of the Weasley family. She is the mother of seven children, including Ron Weasley, who becomes Harry Potter's best friend. Molly is born into the pure-blood Prewett family, being the sister of Gideon and Fabian Prewett. The character is first introduced in "Harry Potter and the Philosopher's Stone", when she kindly tells Harry how to cross the barrier through to Platform Nine and Three-Quarters. In "Harry Potter and the Chamber of Secrets", she is furious with Fred, George, and Ron after she discovers that they flew their parents' enchanted car to rescue Harry from his aunt and uncle who had imprisoned him in his room. At the beginning of the school year, Molly sends Ron a Howler, screaming at him in anger that he and Harry flew the family car again, this time to Hogwarts. In "Harry Potter and the Prisoner of Azkaban", the Weasleys win the "Daily Prophet" draw and use the gold on a trip to Egypt to visit Bill. They return to Britain and stay at the Leaky Cauldron with Harry and Hermione. Harry overhears Mr and Mrs Weasley arguing one night about telling Harry the truth about the supposed connection between Sirius Black and Harry; Arthur feels Harry should know the truth but Molly, feeling the truth would terrify him, assures him Harry will be perfectly safe at Hogwarts with Dumbledore's protection, and orders Percy Weasley to keep an eye on Harry at the school. 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. Molly and the Weasleys are staying at the Order headquarters, Number Twelve, Grimmauld Place, in "Harry Potter and the Order of the Phoenix", where she and Sirius fight over how much to tell Harry about the Order's operations.
