Rereading the sixth book I don't understand why Harry thinks of his mother by name:
Neville’s childhood had been blighted by Voldemort just as much as Harry’s had, but Neville had no idea how close he had come to having Harry’s destiny. The prophecy could have referred to either of them, yet, for his own inscrutable reasons, Voldemort had chosen to believe that Harry was the one meant. Had Voldemort chosen Neville, it would be Neville sitting opposite Harry bearing the lightning-shaped scar and the weight of the prophecy. . . . Or would it? Would Neville’s mother have died to save him, as Lily had died for Harry? Surely she would. . . . But what if she had been unable to stand between her son and Voldemort? Would there then have been no “Chosen One” at all? An empty seat where Neville now sat and a scarless Harry who would have been kissed good-bye by his own mother, not Ron’s?
