Christmas is coming, Umbridge is quietly being driven mad by Severus Snape’s potions, and Hogwarts is starting to notice that Harry Potter is not the same boy who came back from the graveyard. While Umbridge staggers through classes on no sleep, Neville sneaks off to buy his own wand and Harry’s grades keep climbing. That night everything tilts when Harry has his first real vision in months. Inside Nagini’s body, he watches Arthur Weasley attacked outside the Hall of Prophecy. Waking in agony, Harry ignores Dumbledore and runs straight to the dungeons, where Snape catches him as he collapses, takes his warning seriously, and risks a covert trip to the Ministry and St Mungo’s to save Arthur. Morning brings hard truth about the Horcrux link, a plan to contain it again, and the first time Severus quietly tells Harry he is proud of him.
