At the end of chapter six they are riding the Hogwarts Express back to London to begin their summer break. Un fortunately the beginning of chapter seven takes us back to their Christmas break.
nothing like telling an orphan that the stick that chose him is related to the one that made him an orphan is cruel. and when he hides his talent proves he is an idiot. and that everything he physically does is known by everyone proves the authors ignore the basic Primal rule of Harry and the prophesy"a power he(Voldy) knows not" how can he know not if every thing he is or does is immediately countered.
why would harry or hermoine like Ron he is a self centered jealous selfish bigoted cruel lazy idiot that is stupid and he is not loyal as they say his only good trait is strategy.
