Returning to the castle, Edward followed Quinn back, it was only them two for now. When the Royal knight was to come by later, they would bring Paul along with them and would stay there for the process.
When Edward looked at Quinn, for some reason now when looking at his back, it looked a little bigger. He was able to deal with everything that was thrown his way, and in the end, had gotten a good outcome for himself.
But Edward was a little saddened by what had happened, yes he was happy for Quinn, but he was hoping Quinn would stay so he could help out the people. If he was to leave now so soon, then the tenth's people would be in the same position as they were before, being treated as if they were at the bottom of the barrel.
Edward had seen them endure hardships and trouble for so long, he wanted to change that, and after fighting with them against the humans, he felt like it was the first step in a new direction. Now, they had moved several steps back.
