Flashback:
Narcissa Black was excited. She was on the train to her school; Hogwarts, for the first time. She had said goodbye to her parents a few minutes earlier, and to her parent figures; Dorea and Charlus Potter yesterday. She had sat on the train with Sirius Black; her cousin and James Potter; her cousins friend, who she had been introduced to as "a good sort". They talked of Houses and when they finally got there vowed to be friends.
She sat on the sorting stool and the hat was placed on her head. It shouted "GRYFFINDOR!". Her sister Bellatrix at the Slytherin table, scowled. Andromeda at the Ravenclaw table smiled. Sirius grinned, so did James.
