Oh, snap, plot twist - WHERE IS YOUR OMNIPOTENCE NOW, CANARIA??!! *ojou-sma laugh*
What strikes me as interesting (and a bit meta) is that the MC described Canaria as a selfish idiot in the book, someone Cesar could never bond with. Here, meeting Gracy, we're not given any reason to believe she's the sort of kind, pure girl who could "heal the Prince's broken heart" *bleargh* but more of a savvy operator who will fight for what she wants with the weapons available. A much more suitable ally for future king. I loike it a lot.
Also, the whole, "You're going to live and come back because I'm not going to no freaking conventmonastery" is less inspirational than, "Spartan! With your shield, or on it," but I'll take it.
