Here Harry gets an affirmation that he truly does have real friends for the first time in his life. Not only Ron but upper classmates Fred and George Weasley who while they're up to doing ANY kind of mischief are still willing to risk trouble for a friend of their brother. Besides, how many times do you get to fly a car?
Quietly as possible they break Harry out of his "prison", with the twins resorting to getting Harry's school things using a Muggle b&e technique out of a technicality but one they still find useful none-the-less.
In the rush to get out before they get caught Harry nearly forgets Hedwig and the bird's cries of attention waken Vernon to a rage which is compounded further by seeing that Harry is nearly fixed to escape. An act of final desperation allows Harry to safely get away and Vernon again flat on his face.
Matters of being incommunicado are explained to each other and the Weasleys are aghast that a common house elf was behind it all. Dobby's connection to Harry's nemisis is immediately apparent to them.
A safe arrival at the Burrow and escaping trouble seems almost certain if not for Mrs. Weasley knowing her family all too well. After the resultant storm Harry is fondly welcomed to what will become one of his favorite places on earth. The Burrow. Even for a new wizard and been exposed to the magic of Hogwarts, the place is full of wonder and surprises as all sorts of objects and everyday household items are bewitched to make a Witches life that much easier.
The Burrow is nothing more than a tall shack which immediately identifies the occupants' financial state. Being poor for most of his life Harry isn't put off one bit. He feels at home immediately and for once (outside of school) feels free.
Yet freedom doesn't mean idleness as Mrs Weasley puts Harry to work around the house just as she would if he were her own. Working with Ron he finds out the difference between a Muggle's view of a "magical creature" and the real thing. Gnomes, ugly nasty things which are considered pests along the lines of cockroaches as they usually eventually come back. Even then, Harry finds sport as the boys show him a popular method of getting rid of the blighters.
Enter Arthur Weasley who will become a fan favorite in the books to come.
It's easy to see why immediately. His almost childlike glee over all things Muggle, including the Muggles themselves endears us to him. Even his job at the ministry of magic encourages his love of muggle things.
Finding out the trouble the boys are in, he still can't help himself to see how well his own (illegal) enchantment worked before receiving a warning look from his wife. As she begins to lay into him Ron artfully pulls Harry away and leads him up to his room.
Enroute Harry catches only a glimpse of the only (other) girl in the house, young Ginny before continuing on to Ron's bedroom. Inside it's the average teenager's bedroom; a mess, favorite sports team posters plastering the walls, school books and things scattered throughout and other assorted (enchanted) items.
When Ron is apologetic about the size and state of his room (including it's location -- beneath the family ghoul's sleeping quarters in the house attic) Harry beams at him and expresses his delight...
Same here Harry, same here."This is the best house I've ever been in."
