A lot of people believe in magic without knowing it or accepting it.
Nadine, you would think she hated magic, she is often portrayed on this site as hating witches and magic and attributing anything magical to Satan, but that's not the way she actually is. She is a faithful, insecure girl with a good heart, whose faith is important to her, it's where she feels safe and accepted and loved, and sometimes that's all you have. And her faith is based in a magical belief, an idea that miracles can happen. That on occasion God looks down on us and takes pity and changes things. The only difference between a prayer and a wish is the sounds the words make when you say them. And so Nadine wished for all the things that most girls wish for. She wished she was better, she wished she had confidence, that she was pretty, that people would stop being mean, she wanted the world to be nicer and was constantly disappointed by it, but she held out hope that it would all change one day. That God would come back and fix it all in some giant magical moment of truth revealed and lives changed, that she would be transfigured in the glory of the lord, made beautiful in his light and shine like a beacon for all to see. Really she just wished she wasn't so plain, and this all was female power fantasy....but it was earnest, and she did, in the way back of her mind, at least hope that it would happen one day.
Kayla, didn't believe in magic per say, she believed in science. Which is the opposite. But Science is magic we understand, and so in that way she believed in magic too. Kayla saw the world as a place to be understood, a place full of mystery to be broken down and rebuilt. To her the world was magic because she didn't understand it, and there was so much unknown to find out and know. She believed in all the things she could find and see and test, she loved science not for the things that science knew, but for the things that science had shown us that we didn't know yet. And she loved the little magics that science has given us that we all forget are magical. That we can travel in the sky across lands in hours. That we can talk to our mothers in Canada while on a trip in Mexico, that we can see long dead stars in the sky explode with a piece of glass and a tube. But of all the things science is, the thing that obsessed Kayla the most was the future. She hoped for the day when she knew enough to do something, to find something new, she dreamed of the woman she would become, of seeing the stars. To her the future was about becoming, about changing and transmuting and evolving, all of the doings of the world that she cared about were just out of her reach, more than anything Kayla longed for the magical world of tomorrow.
