Her mother was a fox, and her father was a wolf.The two met at a bar and had a couple nights together. When her mother got pregnant and they learned they were twins, they agreed to separate the twins as neither wanted to keep both and didn't want to trouble of putting the kids into foster care. Rosie stayed with her mom, while her brother, Walter(a wolf), stayed with his dad. The two never learned of each other's existence until they met in college. Rosie got her father's eyes, and Walter his mother's eyes. Rosie and her mother lived on the streets/in abandoned households for most of their lives. Rosie got her education viva thrown away homework and some nice teachers. Her mother never sent her to school or even really tried to teach her anything. Rosie's mother kept Rosie but somewhere along the line(around when Rosie didn't have to breastfeed anymore) she began wishing she hadn't agreed to keeping the child. Because now she had to share food with her child, and the kid didn't just thrive off of her. Rosie grew up moving from place to place, being kicked around by most everyone, but she wanted to keep learning and that's what kept her going. Rosie was a naturally curious person, she wanted to know everything. She eventually started getting more and more interested to social psychology, social norms, and how people worked.
Rosie is mute!!! She's shy and off-putting, she gives the vibe of 'leave me alone'. She was able to get into the college because it kind of just accepted anyone, no matter who applied, as long as they had some kind of education and they passed a certain test! (Which Rosie barely passed and her education barely passed.) She doesn't know sign language, but she can write! Rosie can read, write, and even work a computer! However she's not that good at tech, and her writing is messy.
