Ron got hurt - 5

"Okay, Harry," she said, nodding resolutely.

Hermione removed the spell from Wormtail and, using her wand, made him walk in front of her as a shield. Snape had no problem firing at Wormtail, however, and he Stunned him before aiming at Hermione.

"Stupefy," Harry shouted, diverting Snape's attention.

"Always playing the hero, aren't you, Potter? You're just as arrogant as your father, and you're bound to meet the same end," Snape said silkily. The contempt shone from his black eyes as he advanced on Harry.

"You're not half the man my father was, and never will be. That's where all this bitterness really comes from, isn't it, Snape? You know you'll never be as good. You've got a bit of an inferiority complex, I think," Harry said, pleased with the flash of anger that showed on Snape's face.

"Sectumsempra," Snape hissed. The intensity of curses Snape fired at Harry intensified, and Harry knew he'd struck a nerve.

"Your inability to shield your mind will be your downfall, Potter. Your frustration is making you sloppy, and the Dark Lord will have an easy time of it with you," Snape said, sneering. Harry could tell that Snape was enjoying the anticipation of that final confrontation.

"I don't know," Harry replied, panting. "He's certainly made the effort, but hasn't had much luck, yet."

"Don't mistake your good fortune for any measure of skill or talent," Snape spat.

"Dumbledore gave you everything. He gave you a chance and believed in you when no one else ever thought you were worth the effort, and you betrayed him," Harry said, sending a Blasting Hex Snape's way.

Snape blocked it. "I gave him the best years of my life," he said, snarling. "He wasted my talents by leaving me to child mind a bunch of sniveling idiots. I should have been so much more. I was the hero of the first war, but you got all the glory, and then I was expected to protect you. The Chosen One! If you are the only hope of the wizarding world, Potter, it wasn't difficult to see which side would win. There's no one left to protect you now."

Overwhelmed with rage and frustration, Harry let loose a series of curses at the advancing Snape, but Snape remained one step ahead of him, able to deftly read Harry's thoughts and plan his counter curses.

Harry stumbled and fell backwards, watching as Snape advanced toward him. His face was screwed up in an expression of intense loathing, and Harry was left without a doubt that Snape wanted to humiliate him and make him suffer simply for who he was. But Harry also realized his advantage. Snape wouldn't truly do anything to harm him – he was still following Voldemort's orders.

"That's right, Potter. The Dark Lord wants the pleasure of killing you himself, but that doesn't mean he'll mind if I toy with you beforehand," Snape said, answering Harry's unspoken thoughts. "That's the way your dear dead father liked to do things, after all. He never fought without his little gang backing him up and doing the dirty work for him. Never once did he face me in a fair fight. Oh, no, he was much too cowardly for that."

Harry had heard enough. He'd had to fight his way away from bullies long before he'd ever learned to use a wand. In one smooth motion, he leaped to his feet, lunged forward, and delivered a strong right hook to his former Potion master's jaw. He felt several of Snape's teeth loosen on impact.
