“Snape raised his wand and pointed it directly at Dumbledore."Avada Kedavra!”

“Draco, do it, or stand aside so one of us -" screeched the woman, but at that precise moment the door to the ramparts burst open once more and there stood Snape, his wand clutched in his hand as his black eyes swept the scene, from Dumbledore slumped against the wall, to the four Death Eaters, including the enraged werewolf, and Malfoy."We've got a problem, Snape," said the lumpy Amycus, whose eyes and wand were fixed alike upon Dumbledore, "the boy doesn't seem able -"But somebody else had spoken Snape's name, quite softly."Severus ..."The sound frightened Harry beyond anything he had experienced all evening. For the first time, Dumbledore was pleading.Snape said nothing, but walked forwards and pushed Malfoy roughly out of the way. The three Death Eaters fell back without a word. Even the werewolf seemed cowed.Snape gazed for a moment at Dumbledore, and there was revulsion and hatred etched in the harsh lines of his face."Severus ... please ..."Snape raised his wand and pointed it directly at Dumbledore. "Avada Kedavra!”

Harry’s scream of horror never left him; silent and unmoving, he was forced to watch as Dumbledore was blasted into the air. For a split second, he seemed to hang suspended beneath the shining skull, and then he fell slowly backward, like a great rag doll, over the battlements and out of sight.”

“But this is touching, Severus,” said Dumbledore seriously. “Have you grown to care for the boy, after all?”“For him?” shouted Snape. “Expecto Patronum!”From the tip of his wand burst the silver doe. She landed on the office floor, bounded once across the office, and soared out of the window. Dumbledore watched her fly away, and as her silvery glow faded he turned back to Snape, and his eyes were full of tears.“After all this time?”“Always,” said Snape.”

“Severus Snape wasn't yours," said Harry. "Snape was Dumbledores, Dumbledores from the moment you started hunting down my mother...”

“I heard from my dear friend Tiberius Ogden, that you can produce a Patronus? For a bonus point...?Harry raised his wand, looked directly at Umbridge, and imagined her being sacked.Expecto Patronum!The silver stag erupted from the end of his wand and cantered the length of the hall.”
