Madame seems flat, as a character that is

"We called her "Madame" because she was French Belgian- there was a dispute as to which- and that was what the guardians always called her. She was tall, narrow woman with short hair, probably quite young still, though at the time we wouldn't have thought of her as such. She always wore a sharp grey suit, and unlike the gardeners, unlike the drivers who brought in our supplies- unlike virtually anyone else who came in from outside- she wouldn't talk to use and kept us at a distance with her chilly look." Kathy page 32
If there is one character that seems utterly one dimensional it's Madame. Every time we've encountered her she seems cold and disgusted almost. Kath even makes the observation that she views the children as spiders or vial creatures she doesn't want to touch. She seems to be scared of them in a way as well. And yet she is connected to this whole idea of the Gallery. So why is this uptight lady who seems to be scared of children come to a school full of kids to collect the art they created? Also there's the whole incident when Kath catches her watching her dance to the song "Never Let Me Go" and she's crying. Why would she be crying for a child she seems to dislike so much? Maybe she's more dynamic than she appears but for now she seems completely one dimensional.
