Draco’s lip curled but he jerked off a nod, saving his breath. Longbottom raced toward the library, back into battle, and Draco hobbled after him. He spat on the body of the witch who had tried to Incendio him as he limped awkwardly past it. She would have burnt him alive if Longbottom hadn’t put him out with what had felt like a lake’s worth of water. Draco had used the Killing Curse on her for that; blinded by pain, falling to the plush carpet, but with wand arm out and mouth spitting the words. They had felt like greasy ashes on his tongue, but revenge had been good.
