Harry Potter and the Deathly Hallows
Chapter 3 - The Dursleys Departing
Harry is pulled out of his memories from Dumbledore by his uncle Vernon. Uncle Vernon changes his mind every day. He is now once more convinced that Harry and the Order are after the house. Harry tries to convince him that they are in real danger, because the spell, which protects the house, will loose its power when he becomes 18. Kingsley Shacklebolt and Arthur Weasley already tried to explain the situation to the Dursleys, but Vernon isn’t sure and has every day a new opinion about leaving the house.
After a short farewell scene in which Dudley thanks Harry for saving his life, he explains to leave the house. His parents, who won’t let him leave alone, leave the house with Daedalus Diggle and Hestia Jones.
