She gets ignored or talked over so often,treated quite differently to the other chuldrun,Lazy in particular clearly can't be arsed when Isla is speaking,she frequently rolls her eyes or totalky ignores Isla.Isla was the only one who enjoyed school before they were taken out. She still seemed to have friends there. She likes learning and has been interested in a variety of topics, where she obviously takes the information in but doesn't get any direction of what to learn.
She wants to be more sociable and was the only one that wanted to do some kind of activity. I don't know whether dance will actually happen but even that seems a bit like it's been chosen because it was the only thing Esme would also do. Isla might like dance, but it feels a bit like she would do better doing something that is just for her, and let her explore something new. She doesn't go to school so I don't know why she is restricted to just one club (which probably won't happen anyway).
She was the one that wanted more books but they didn't know what to buy. Eventually she got a few (mostly for younger readers) but I have not seen any more. They never mentioned taking her to choose any for herself.
She doesn't have a sibling close enough in age to play with, and doesn't seem to have anything in common with the rest of the family other than getting overexcited about treats and shein hauls.
Isla wants to learn but poor child has an empty life stuck with the Madams family
