Well...I don't think any Eternano within the body is ever contorted until one person actually attempts to learn some sort of magic. While you can have a certain affinity in the progress of learning magic once you've begun learning it (maybe through genetics like Aivenna and Kristen), I think all magic within the body is entirely stagnant if you possess it, until you've made the effort to learn a magic. Of course, the ability to learn this magic is completely dependent on the person, such as Chelia learning God Slayer Magic surprisingly early, Erza learning Requip and so forth. But yeah, that's my personal opinion on it: magic is stagnant or undisturbed within the body until you've actually attempted to learn it.
