Third year of Hogwarts..

Giulia Potter, a few months older than her brother, Harry Potter. She went into Slytherin, at first Ron was put off, but then he realized that didn't describe the person.

Ron was always very close to the Potter brothers, and could tell he had a crush on his best friend's sister...

They were in the Great Hall, studying. Ron was only wearing the white part of his uniform, his Gryffindor tie and his pants. Everything was fine, until some Gryffindor student announced that Sirius Black had been spotted! He had the newspaper in his hands. When he says this, everyone who was there gathered around, including Ron, Giulia, Harry and Hermione.
