It happened without any intervention or sign from the Head Table, as the students had finished their subdued dinner; it happened with no permission or forgiveness asked from the Professors or the Headmaster.
Shortly after the dessert dishes had appeared, a student stood up from the Slytherin Table and calmly made his way, not to the front of the Head Table, but toward the opposite side of the Four Tables of Hogwarts. A few whispers broke out at the sight of the white-blonde short-cropped hair, as Draco Malfoy stood there, silently regarding all of Hogwarts. Draco Malfoy had said almost nothing since his surprise return. The Slytherin had condescended neither to confirm nor deny that he had returned because, with Hermione Granger dead at his family's hand, he no longer had anything to fear.
Then Draco Malfoy took up a spoon in one hand, and a glass of water in the other, and began tapping, producing a clear ringing sound.
It produced more excited babble at first. At the Head Table, the various Professors looked in puzzlement toward the Headmaster in his great chair, but the Headmaster gave no sign, and so the faculty did nothing.
Draco Malfoy continued tapping the spoon upon his glass, until the room fell silent, waiting.
Then another student arose from the Ravenclaw table, and made his way to where Draco Malfoy was standing, turning to face Hogwarts at his side. Breaths were drawn in surprise; those two should have been the bitterest of enemies -
"I, and my Father, the Lord of the Noble and Most Ancient House of Malfoy," Draco Malfoy said in a clear voice, "have come to realize that there are ill forces at work in Hogwarts. That these ill forces, did wish Hermione Granger harm. That Hermione Granger was perhaps compelled, against her will, to raise her hand against our House; or perhaps she and I were both Memory-Charmed. We now say that whoever dared use the heir of Malfoy so, is the enemy of House Malfoy, upon whom we shall have our vengeance. And that honor be served, we have returned all moneys taken from House Potter, and canceled all debt."
Then Harry Potter spoke. "House Potter acknowledges that it was an honest mistake, and holds House Malfoy no ill will. We believe and publicly say that House Malfoy was not at fault in Hermione Granger's death. Whoever harmed Hermione Granger is the enemy of House Potter, upon whom we shall have our vengeance. Both of us."
Then Harry Potter began to walk back to the Ravenclaw table, and the babble of sheer, utter, reality-crashing bewilderment began to explode -
Draco Malfoy resumed tapping his spoon against his waterglass, creating a clear ringing chime.
And other students arose, from other tables, making their way to where Draco Malfoy stood, arranging themselves at his side, or behind him, or before him.
There was a dread silence in the Great Hall, a sense of the world shifting, of realigning Powers, almost tangible in the air.
"My father, Owen Greengrass, with the consent and full backing of my mother, the Lady of the Noble and Most Ancient House of Greengrass," Daphne Greengrass spoke.
"And my forefather, Charles, of the House of Nott," said the former Lieutenant Nott, once Theodore of Chaos, now standing behind Draco Malfoy.
"And my grand-aunt, Amelia, of the House of Bones, also Director of the Department of Magical Law Enforcement," said Susan Bones, who stood anext Daphne Greengrass, beside whom she had fought.
"And my grandmother, Augusta, of the Noble and Most Ancient House of Longbottom," said Neville Longbottom, who had returned for this one night.
"And my father, Lucius, the Lord Malfoy, of the Noble and Most Ancient House of Malfoy!"
"Together with Alanna Howe constituting a majority of the Hogwarts Board of Governors!" Daphne Greengrass said clearly. "Have, to ensure the safety of all students, including their own children, passed the following Educational Decrees upon the Hogwarts School of Witchcraft and Wizardry!"
"First!" Daphne said. Daphne was trying to keep her trembling under control, as she faced the Four Houses at the forefront of the five. There was only so far her parents' lessons in speech-making could take her. Daphne's eyes darted down quickly to her hand, upon which, written with a quill in faint red ink, cues to her lines had been written. "Students are not to go anywhere alone, not even to the toilets! You will travel in groups of at least three, and every group must have a sixth-year or seventh-year student!"
"Second!" Susan Bones said from behind her, voice almost firm. "To further ensure the students' safety, nine Aurors have been dispatched to Hogwarts to form an Auxiliary Protective Force!" Susan took a small, round glass object from within her robes, one of the communicators that the DMLE used, which they'd all been given. Susan raised it to her mouth and said, her voice now higher, "Auror Brodski, this is Susan Bones.
The doors to the Hall slammed open, and in marched nine Aurors in the reinforced leather gear they used when on duty. At once they spread out, two Aurors taking up station by each of the four tables, and the last took up watch at the Head Table. There were more gasps.
"Third!" said Draco Malfoy, his voice commanding. Malfoy had apparently memorized his own lines, since there was nothing written on his hand that Daphne could see. "In the face of a common enemy who does not balk at killing students from any House, the four Houses of Hogwarts must come together and act as one! To emphasize this, the House Points system is temporarily suspended!
"Fourth!" recited Neville Longbottom. "All students not already in the Defense Professor's after-school classes, will receive special training in self-defense by Auror instructors!"
