I know that you are probably tired of reading these at the top of fanfics by now, so I'll make it short: I don't own Harry Potter.
With a small pop a man appeared in the middle of the street. His black cloak was moving gently with the fall breeze, as he walked briskly to the ruined house at the end of the lane.
The gate was splintered, hanging by one hinge, and the door to the house was gone. Severus Snape stumbled through the door into the ruined house. In the hall lay a man, the very man he had hated for so many years.
James Potter's body was unmoving, broken, peaceful. Severus felt a pain in his heart as he looked down at the man he had loathed for so long. He hadn't wanted him dead.
He staggered up the broken stairs, and into the nursery. There, in the center of the room, surrounded by discarded toys, lay his best friend, the love of his life. Lily Evans.
Her fiery red hair was spread out around her, and her emerald eyes were shut, never to open again. Severus felt his heart break in two as he looked at the girl he had first admired so many years ago at the park. Clutched in her hand was a baby rattle, in the shape of a Snitch. Severs pulled her close and cried. He felt her hair brush against his skin, and his heart broke again when he remembered that day in their fifth year when he had called her the unforgivable name; Mudblood.
Severus hated himself. If he hadn't called her that, then she would've lived, he wouldn't be here, clutching her dead body to him in a desperate attempt to bring her back.
His eyes shifted to the little baby crying in the crib. Harry. His eyes were brilliant emerald green, the same exact eyes that were Lily's. And on his forehead was a scar, a lightning-bolt shaped scar.
Severus turned from the baby and left the nursery. He stumbled back down the stairs and out into the cold night. Never again would Lily Evans's eyes open, never again would they light up with laughter. Never again would Severs Snape hold Lily in his arms. Never again.
