Harry yells back.
From Create Your Own Story
Having had enough of his Uncle's yelling, screaming, and general behavior, Harry shouts back, “Shut up you fat piece of shite! Leave me the fuck alone!”
“WHAT DID YOU SAY TO ME, BOY!”
“I said, SHUT THE FUCK UP AND LEAVE ME ALONE YOU BIG, FAT PIECE OF SHITE!!!”
“AAARGH!!!” Vernon shouted from behind the door. It was the sort of sound that would have made a hardened criminal whimper. This guttural, loud growl was followed by the door rattling violently. Then...
BANG!
BAAANG!
Harry leapt up off the bed, rage rushing through his veins. Stomping over to his bedroom door, he wrenched the door open, and found his uncle starting madly at him.
"WHAT THE FUCK DO YOU WANT!?" Harry shouted, his face just a foot away from Vernon.
Not bothering to say a word, Vernon's response was swift and sudden. He balled up his fist and punched Harry in the face. The force of the punch sent Harry stumbling backward and falling to the floor. Harry's hands immediately went to his face, where blood was pouring from his nose. It was far from the first time he'd suffered a broken nose. Dudley had given him many others.
Seeing his own blood on his hands, and his uncle standing over him, looking like the proverbial cat that ate the canary, something inside Harry snapped. Rage and anger came from a place deep inside him. A rush of pure power ran through his body. The hair's on his arms stood straight up, as if someone had taken a balloon and rubbed him repeatedly, charging him with static electricity. But this was no minor electrical charge. This was pure power, pure magic.
He closed his eyes, and felt a pain like never before erupt from his scar. His body began thrashing around uncontrollably, the pain unbearable. Harry's screamed, the sound piercing the silent night. His shriek was primordial, reverberating throughout the house.
As the pain began to fade, he saw a life flash before his eyes, memories foreign to his own. 'I've always heard about before someone dies, they see their life flash before their eyes, but this is... Weird... This is not MY life...' Then it dawned on Harry just whose life he was seeing.
Voldemort! Harry saw flashes of Tom Riddle's life: the orphanage, meeting Dumbledore for the first time, finding the Chamber of Secrets, creating his Horcruxes, etc. He felt connected to Tom Riddle at a deep, personal level, feeling the anger and rage within him.
Suddenly, his eyes snapped open, the whites of his eyes stained red with anger, focusing on his uncle, his next move all but certain.
