Harry’s bad feeling proves right the moment Snape is forced away, and Harry moves fast. He sends Dobby to Malfoy Manor to retrieve Luna and stop Neville from doing something reckless, then races to regroup as Dementors close in around an almost empty Hogwarts. In the Headmaster’s office, Harry, Snape, Luna, and Neville scramble for information, summon Kreacher, and recover the Marauder’s Map. When the map reveals Tom Riddle entering the castle and Death Eaters gathering at the gates, they shift from survival to strategy, coordinating House-Elves, the Floo Network, and the Order to get students to safety before the castle becomes a battlefield.
