Lucas Flint
Lucas Flint was sorted into Gryffindor, though his father had a bigger problem with it than he did in the Redux-verse. Lucas had a few run-ins with Umbridge and did get to experience the infamous quill, which he never told his siblings about. Though his father was a Death Eater, which meant that the Carrows were at least somewhat predisposed to tolerating him, Lucas couldn't always keep his mouth shut, nor was he very good at their brand of 'Defense' or 'Muggle Studies' and had detention with them a fair bit, which included rounds of the Cruciatus Curse, which resulted in permanent nerve damage. Again, he never revealed this to his siblings until it was far too late.
Lucas finished school like many of his peers, more than a bit traumatized and a little bit ostracized because of his father's choices during the War. He never becomes an animagus. He went work at the Dragon reserve in Romania, but far more cynical, bitter, and angry than the young man we know.
