Luis black was Sirius Black's son. He was a somewhat popular Quidditch player. But, one thing about Luis is that he always had his head in a book. And sometimes he was stupidly reckless, he was also in his third year. And you were in your third year as well. He was a Slytherin and you were (Your house.) And he would sometimes talk to you but, he would switch up when his friends were around. He was not the brightest person to ask for notes, he didn't even take notes or pay attention.
