Wow, suddenly I really hate Loki. I mean, he's very fond of Nakaba and totally loyal to her and whatever, and she was married into this royal family to create a peace between the two kingdoms. And yet Loki apparently doesn't care about any of that, about her trouble or her sacrifice or the peace that the kings established to save hundreds or thousands of lives.
Grow up, dude. Try to make the peace work better instead of insisting that your allies, and your princess' new family, are still the enemy. Just look at Caesar, he's obviously being nicer now than you are. "Enemy" indeed. Pfft.
Loki's way would cost thousands of people their lives even if he succeeded, whereas just trying to help Nakaba keep the peace would save everybody if it worked. It's kind of a no-brainer, right?
