The only one he ever trusted

Starting from OotP chapter 22. Harry just had his vision and is led to Dumbledore's office along with Ron. Harry discovers himself to be more powerful than he seems, Dumbledore makes better choices too. An abused child is wounded for life, and it takes more than just friends to heal. Only 3 Horcruxes (I do not have JKR talent nor do I own her magical universe).
