Andromeda- Perilous on the Cliff
Andromeda sincerely hoped the Sorting Hat placed her in Slytherin. She knew it took into account what the person asked, so she felt she'd be alright. If she wasn't in Slytherin, she was sure she'd be disowned.
She knew she wasn't like her sisters. Bellatrix lectured about inferior Mudbloods and the Black family's pure blood to her as soon as she got back from Hogwarts. Even Narcissa, the delicate person she was, stuck up her nose at anyone who was not pureblooded. Andromeda secretly hated the pureblood ideals but she'd never tell them that.
Her only confidante was their cousin Sirius Black who harbored her same feelings.
"Why don't you just let the Hat sort you into another house then? If you feel the same way I do. That's what I'm going to do. I hope I'm in Gryffindor." he whispered to her on the train there.
Her eyes opened in shock. "But Sirius, you can't- you'd be disowned. Sweet Merlin, Gryffindor, they're Slytherin's rival house. Bella will hex you."
He shrugged, "I want to see Mother and Father's face. I don't care what they do to me."
"I do!" she told him.
They sorted them alphabetically, Andromeda first since A goes before S. She could see Bella's smirking face out of the corner of her eyes. She trembled as the Hat was placed on her head.
"Are you sure you want Slytherin? Ravenclaw seems like a place where you would fit well." the Hat asked her. She was afraid to shake her head lest Bella realized what was going on and drilled her later. Finally, she persevered. After hearing the Hat bark out Slytherin and walking down to the smiling faces and pats on the back, she had never felt more relieved.
But then it was Sirius' turn. He swaggered over to the Hat with utmost confidence. As soon as it was placed on his head, he smiled widely. The Hat opened its mouth and uttered the forbidden word, the final straw.
"Gryffindor!"
As the Slytherin's faces fell and the other tables tittered, Sirius met Andromeda's eye and mouthed two words while pointing a finger at himself that made her pale, blood traitor.
She knew it was only going to get worse from there.
