|“||[Hammond] is so busy fanning disputes in other countries, he hardly ever sees his daughter.||”|
Rosaly has chin-length, light brown hair, with thin, long eyebrows, long, faded blue eyes, and a diamond-shaped face. Her outfit consists of high-waisted red jeans, a cropped salmon tank top, platform sandals, a thin beaded choker, and two pink stud earrings. She is fair-skinned and wears light-pink lipstick.
The two then enter a hotel room, where Hammond explained to Rosaly that he had business in Ulgia and could not be bothered by her. She began to yell that this is why her mother divorced him, but stopped herself. He told her to go home on the outgoing flight the next day while she asked if she could stay for two days, to which he declined. She then reminded him that her birthday was in two days, which he had forgotten.
Later that night, Kirika stared at a picture of Rosaly eating ice cream with a friend. She started to reminisce about when she first came to, and compared herself to Rosaly.
While Rosaly is sleeping that night, Hammond entered her room to tell her that she would be going home to New York next week instead of the next day. She became elated at hearing this.
As Rosaly walked down the sidewalk the next day, carrying a bag of groceries, she passed Kirika, who had just finished killing her father. Rosaly dropped an orange on the ground in front of Kirika, who picked it up and handed it to her. Much to Rosaly's confusion, she walked away without saying much, as Rosaly continued to walk towards her father's office.
