Xanthe was worried. Lucy was becoming too powerful, too fast. There was nothing wrong with being powerful, of course, but only if one went about it the right way- by learning, and studying, and becoming more mature and wise as you do so.
A nine-year old with as much power as Lucy seemed to have was about as dangerous as a monkey with several nuclear missiles. Not that Lucy was a monkey, of course; monkeys were, on the whole, far more sensible than nine year olds.
To be fair to Lucy, though, she did seem to be more sensible than most children her age-and Xanthe thanked her lucky stars that Lucy wasn't a boy of the same age, as young boys are generally much less willing to play nice than young girls. It probably helped that Lucy herself was not entirely aware of just how much power she could wield-that and the girl didn't have the nature or general temperament of those who became dark spirits.
If Xanthe herself, on the other hand, had had access to power such as Lucy's- maybe not at that age, but certainly during her teenage years- the situation would have been very different. Lucy, at least, had good friends to keep her in check whenever she got a little too big for her britches.
Though whether that would be enough... only time would tell.
This is just a little drabble that I wrote ages ago. I just thought I'd publish it to see what kind of reaction it got, as well as add to the tragically small amount of Stardust fanfiction available. Please read and review! :)
