Molly Weasley started off by telling her how lovely she looked in spite of a 12 hour drive, she thought it was strange that she had also driven Malfoy home but Ginny had come to her rescue and helped defend his new found character, Molly just gave her a hug and told her to be careful around her new friends. Mr Weasley gave her a huge hug and asked her all the details about her drive, he wanted to know everything about the manoeuvres she had used and what buttons she had pressed. After a 10 minute crash course in driving a manual Muggle car he went out to inspect it; she had reluctantly given him the keys.
