| The people that Neville and Luna supposedly marry should not be included, as it did not actually happen in the books. What Rowling imagines, but did not include, is not actually part of HP lore. Also, she contradicts herself, as in the epilogue of Deathly Hallows she clearly indicates that Neville is a professor, whereas in some interview she said Neville marries Hannah Abbott and runs some shop.
Go by the rule that if it didn't happen in the books, it didn't happen. |
