I find them interesting =)
*The only person she views as a parental figure is Karen.
*Brooke's parents have been absent most part of her life. They are almost always away on business trips, leaving Brooke alone in their big house in Tree Hill. In Brooke's senior year, they moved to California, but Brooke stayed in Tree Hill to finish High School there. Her parents absence is a big part to why Brooke feels so insecure about love, and why she has fears of never being enough.
*Brooke likes to make up nicknames for her friends. She calls Peyton "Best Friend", "P.Sawyer", "Curly Head" and "Fake Blondie", Lucas "Broody" and "Boyfriend", Mouth "Buddy" or "Lips", Nathan "Married Guy", and Haley "Tutor Girl/Wife/Mom" and she sometimes calls all her friends, just that, "friend".
*Lucas calls Brooke "Cheery", Peyton calls her "B.Davis" while Nathan and Haley just call her Brooke.
*Brooke Davis's hair style and/or colour often changes based on the characters Sophia Bush is playing in movies since Sophia has shot at least 1 movie a year since the pilot of One Tree Hill.
*Brooke has only said I love you to two guys: Chase Adams and Lucas Scott.
*Brooke has never dated a blonde guy on the show, except for Lucas. She often seems to date his opposites. Felix in season 2, who was basically a male clone of Brooke. Nick in season 4, a model/teacher who gave her expensive gifts and Chase in season 4, a virgin who is almost a too perfect boyfriend.
*Brooke's nickname when she went to camp was 'Mouth' because she always slept with her mouth open. She told Mouth this upon finding out his name.
