that would have been nice, but doing the math i'm not sure the timelines would match up for that, maybe she interned at his office before she (with cade's biggest blessing) decides to open her own? he's almost a decade older than her and he opened his office when she was only 25 and still would have been in uni for another year if she went straight away after high school (again if my math is right and the 8 years of schooling it takes).
but that way they could still know each other and have some sort of sibling like relationship?
