A brother may not be a friend, but a friend will always be a brother.
Listen, I remember something. At the start of the year, Stiles was trying to find a place for you guys to live after graduation. He said you were getting an apartment together. And I remember saying something to Stiles. Something like it's not always a good idea to live with your friends. Even your best friend. But Stiles said it wouldn't matter because you weren't just friends. You guys were more like brothers.
