Disclaimer: I do not own Harry Potter.
There was a time when she smelt of bubble gum and chocolate, of youth and innocence. Now she smells like blood and whiskey, age and cynicism.
Once her skin was pale and unblemished, but now its bruised and scarred. The dark mark forever branded on it.
She yearns to go back to being unblemished and innocent. To the days when her hands were not stained with blood and her soul blackened by the things she'd done.
But she can't go back and there is nothing she can do to go back.
So she does the only thing anyone in her position can do, dive into the darkness so deep that she loses her mind and stops caring or wanting to go back.
