I know what you mean by majorly out of character. So far most of the fics I've read that have her in character either have the "soul purified by love" ones, the ones like yours that envolve her mirror, or have some SERIOUSLY far fetched theories(no kidding, I read one one time that had this whole vampire twist to it and something about the vampires dark energy counter acted her own). Either that or they just aren't romance.

And I have read some that are just so OOC that you can't help but just go "...What just happened?!" and then I get a headache. Anyway I'm going off on a tangent. Glad I could help.
