Once again, I do not own Harry Potter. That belongs to J.K. Rowling, one of the best authors I've ever read.
Ollie Black lay in his bed at home, his older brother Caleb sitting next to him. He was dying. He knew that, and Caleb knew that. Everyone else did, too. He was always a small boy, never very strong, but something had gone wrong. He ended up with a sickness no magic could fix. As he lay in bed, his chest moving up and down weakly as he breathed, he knew his time would soon be up, and Death would come for him, carrying him in his arms towards whatever lay beyond death. A tiny smile graced his small, pale face as he thought of how much fun he had had at Hogwarts, managing to finish his first year there despite his poor health. He looked over at Caleb, weakly grasping his brother's hand. "C-Caleb..?" He asked. "W-Will it hurt..?" He asked softly, fear showing in his blue eyes. Caleb gripped his hand gently. "No," he said, his voice shaking as he held in tears. "It won't hurt, Ollie, I promise." Ollie sighed, the ghost of a smile on his face. "Good.." he said. He leaned up and gave Caleb a weak hug. "I'll miss you.." he said, sitting back. Caleb could no longer hold in his tears as Ollie hugged him and wept, grasping his brother's small hand with both of his, tears falling on their hands. "It'll be okay, Caleb..." Ollie said. "I won't be sick anymore.." he said, hating to see his brother, normally so strong, cry. "I know, Ollie." he said. "I know..." Ollie smiled weakly as he took a struggling breath. "I love you, Caleb.." he said, taking his last breath, his bright blue eyes going dull as they closed for the last time, never to reopen. Caleb hugged the boy's still warm body, openly weeping. "Love you, Ollie..." he whispered.
