Eileen still believes she’s the only one who manages hard work in a way that is beneficial to her, helps her practice her magical skills, and rescues the innocent. For her hard work is memorising skills, practising her skills and so on but Jenny doesn’t agree. For her hard work is being up all night with a screaming baby.
The Fairy Queen believes jewellery must have either gold or diamonds in it somewhere to be “proper”. Gold has to be of the purest carat, diamonds to be huge and to catch and reflect the light beautifully. Eileen loves jewellery too though her items are more modest, certainly not in respect of her cousin, but because Eileen has a grave distrust of anything looking flash. Flash = spiv in her books.
Jenny loathes all sport bar tennis and swimming. Eileen, while she doesn’t watch or take part, feels sport is a good thing as it keeps humanity out of mischief. Well she did hold that view until she discovered what football hooligans were. Jenny had to stop her mother turning them all into toads. Humanity may never know how wrong Jenny was here! There are some sports played and watched in the magical world but not with the enthusiasm shown by humans.
Jenny is a Christian (her mother’s tale gives her real dilemmas here too. What is Jenny supposed to do with her unexpected powers? It's hardly something she can share with the vicar) so believes in the Christian view of paradise. Eileen is broadly sympathetic (though wonders whether it’s different for awkward fairy godmothers. She takes some solace from the thought God looks on the heart - even when fighting dragons Eileen has, in her way, always meant well). Eileen hopes to go to heaven eventually but is in no hurry to depart this life.
