Let's say that Wormtail was taken into custody at the end of the 3rd book, Sirius' name was cleared and he was a free man again... I would be very curious to have read how Dumbledore convinces Harry to go back to the Dursley's at the end of each term for the sake of the protection instead of just going straight to the house of his legal guardian....just cause its not till the end of the 5th book (I think) when he tells Harry why he has to go back to the Dursleys at the end of each term.  
   
Would Harry just be like "To hell with it, I'm out!" ? haha
