Madeline Longbottom is a lifetime friend of the Weasleys. She became quick friends with the twins, who are the same age as her, because of their common passion for quidditch and mischief. They never take anything too seriously but the events of this year might force them to be a little bit more prepared for the dangers that are coming Hogwarts' way.
