Vivian starts high school, and it's wonderful.
There's a QSA she can (and does) join. There's political activist groups she can (and does) join. There's Model UN and debate and so many more options than middle school.
She tells her parents about (some of) her clubs. They're delighted she's getting so involved, and that she's so enthusiastic about everything; none of them remember the days of early Saturday Chinese classes fondly. They meet her debate teacher and help her with her Model UN research. When her biology teacher praises her interest in environmental sciences, they even take her to a panel on climate change, and she listens in horrified fascination and asks the coordinators for volunteer information on her way out.
They are noticeably less pleased when she comes home with short, bright and entirely unmagical pink-streaked hair.
The argument itself is actually shorter than she expected, but afterwards her parents are much frostier than they used to be. They don't say anything more, not really, but her mother sighs and her father stares pointedly and they're perfectly well able to make their opinions known without words. It's both what she'd feared and not at all what she'd expected, and she doesn't know how to handle it, so she just complains wistfully to her QSA friends and tops up her dye job and misses what they used to have.
