She was definitely the most intriguing of Albus' cousins, and often the most annoying as well. She was constantly telling everyone off for breaking any rules whatsoever. However her bossy nature just made Scorpius, Albus, and himself go behind her back and pull even more pranks than before she yelled at them. Orion absolutely loved the way her eyes flashed when she caught any member of her own family disobeying her precious rules.
Rose was also very smart, always the top of all her classes. According to Albus she took after her mother. Knowing this, he was incredibly surprised to find her sitting in the potions corridor, crying, with an essay. He was even more surprised to see an "acceptable" along the top of the paper. Seeing no one else in the vicinity, he took it upon his twelve year old self to make her feel better. He sat down next to her and let her cry into his shoulder for a good twenty minutes until the bell rang for dinner. He accompanied her to the common room before making his own way to the great hall after she whispered that she was too embarrassed to eat that night.
The next day she smiled across the hall to him at breakfast, and he knew he had made a good decision to help her. However, neither of them spoke a word about the incident, not to each other or anyone else. Things continued as before, Orion and his friends would break rules and Rose would chastise them. It was a comfortable routine.
