He didn’t disagree with his Aegis, but he knew where his loyalties lay. His vow was to Artorias, and upholding it meant honouring the pack - which he did with love and respect. But at the end of the day, if for some reason Artorias walked away from this pack, and he asked Mercury to follow, he would do so. No doubt, no hesitation. Of course, the chances of that happening were close enough to zero to make no difference. So in the end, it did not matter. He inclined his head to Art and smiled at the man that had so effectively won his loyalty.
When the Aegis drew Embershard and told him to bow his head, he stood formally, and lowered his head with grace. He had been royalty long enough to understand the importance of grandeur. He closed his eyes, and listened to Art’s words, letting them reverberate through them as he felt the touch of cool metal against his fur. He rose when he was commanded, but he dipped his head at Art. “You honour me” he said softly. The change in his rank seemed so sudden, despite having asked for it. He knew he had a lot to do.
