I found the ship pebill and I'm unwell...
Maybe new name: billworm or sybtail?
If I said Sybille was the top of her class in divination and jokingly predicted the future of her ravenclaw friends but never really believed it, since she never had a negative prediction till she went out with Peter. In 6th year she got closer with the nervous yet sweet 7th year gryffindor with the sandy hair and contagious laughter. He jokingly dared her to read his palm,to have a reason to hold hands for the first time. She held his hand and saw horror: betrayal, pain, rats, dark corridors,black cloaks,red haired children, death everywhere, snakes, masks, war. Tears streamed down her eyes out of fear and got ice cold hands, Peter asked her "What's wrong Billie?". Sybille was sure she was wrong ,she must be. Oh she couldn't tell sweet Peter about that.
Four years later, the war went down exactly like in her prediction, snakes everywhere and Peter never had time to see her and always went into hiding, she assumed joining the order was exhausting. At the end he got betrayed by one of his closest friends in a dark alley. Something Sybille never could connect was all the rats and the red-haired little boys from her vision. That's what she thought for 12 years at least. What if she had told someone. Would you hate me?
