I figure she would fit in the game, even though she's younger, because she would pretty much relate better to older people than people her own age. She would be both mature beyond her years at times, and a normal, immature and spoiled brat at others. We can talk more details, I love fleshing things out.
I also would adore an Isla Fischer for the other third of this storyline. She would be the female counterpart of Chris to the Dakota. She also works in the same firm and the Dakota also tails her annoyingly. And, in the process, somehow, she and Chris end up meeting and they sort of become almost parental figures to the kid. Though, romance is not required, you never know where it could end.
And, the game is glossed, btw. And, everyone should join.
