Joey the child is a great character.
Just Joey the adult is a little, say, over drawn. Everything has to be solved by her-even when away in Canada and it then takes a week to get letters backwards and forth, everyone has to adore her, and marvel at her long family.
She would be much nicer if they had provided her with a counterpoint, one of the staff (fairly senior) who would sometimes say "for goodness sake, stop being silly, we can do it ourselves", or "Let's not ask Joey over, she's too overpowering". Or more like Miss Ferrars does with Mary Lou, but more long term.
There is very little link between child Joey-who has bad points as well as good points, and the adult Joey, who is all that is amazing. Can you imagine a bunch of teens going round to someone's house for a party and begging their host to sing? unless they wanted to laugh at them But then also as the adult Joey, suddenly all the history is written and she was amazing, it's regularly said she was the best head girl, when she was actually pretty poor.
Although having said that, you can begin to see the way the character is going during her time as headgirl. There's the point that some of the mistresses object to the way Grizel addresses Joey, because "it's not good for the girls to hear their head girl talked to like that"-when Joey had been just as rude to Grizel before, Grizel was staff! (Camp)
And another time, i think when she's head girl, she waves her hand and knocks the soup being served to her all over another pupil-a junior. The junior is told not to be so silly, and Joey's poor burnt hand is crooned over by Mme.
Think it's New Mistress, but I might be wrong. I cannot work out a way that you could gesticulate and knock the soup all over someone and burn your hand and not burn them worse.
