"I am Cassandra - she who, without asking, understood it all and still came to her fate...," The dark haired girl slowly lifted her eyes from the piece of paper with torn edges that, only a day ago, was found in her robes as she embarked the train that'd take her and Regulus back to Grimmauld Place 12.
She had the slightest idea of who may have slipped it there, but didn't want to get her hopes up.
"And what Muggle book is it now, Cas?"
Cassandra Black stifled her laugh, "Not a book, Reg. Just a poem."
"It's what'll get you a whack from mum if you don't be quiet about it," he shot back coolly.
Cassandra just smiled again and lightly shook her head. She'd let him have the last word as usual. She knew it brought Regulus a small sense of accomplishment and these days, she'd do anything to let him have a happy moment. Walburga had been on him about his grades from the moment they'd arrived home.
Cassandra let her eyes fall, once more, to the small piece of paper in her hand. This time, she spoke low, only for herself to hear, "I, Cassandra, full of visions, who sees her own death without turning away, and hears in the night the day that follows."
