Dazed by the attack, Harry barely had time to react in order to avoid getting crushed by the Horntail’s tail. He jumped out of the way, landing on the ground with a loud thud. He hissed when the jagged gravel and dirt cut through his robes to graze his elbows and forearms, but he shot up to hit feet and sprinted to dodge another plume of fire aimed at him. He fired a Blasting Hex at the dragon, forcing it to stop breathing fire as the spell struck it on the nose. It growled and snapped its jaws at Harry, getting so close that he could have sworn he heard someone (a girl, likely Hermione) shriek in fright. He rolled out of the way and snarled back at the Horntail, then grinned when a sight caught his eye. The Serpent Slayer was on its way.
