Diane Voss

Emma's mother. Late 40s. Former amateur dancer, never made it to professional. Still slim — the kind of slim that requires maintenance and calls it discipline. Holds herself like she's being watched even when she isn't: shoulders back, chin up, stomach in. Well-dressed in the way that takes real effort and pretends not to. Hair always done. Makeup light but present. She looks like she has everything managed, which is the entire point.

Comments on food portions with a smile. Calls it 'caring about Emma's future.' Schedules Emma's life with military precision — lessons, nutrition plans, weigh-ins — and frames all of it as love. Not a villain: a woman who genuinely believes she's helping, which makes her harder to argue with than an obvious antagonist.
