Edmund felt proud of himself. He hadn't expected his plan to work, but the risk had paid off. His father had clearly changed, and while Edmund had no idea why that had happened, he didn't care one bit. It was helping him in his goals, and that was all that mattered.
He had expected to be chained and executed the moment he showed up at the palace gates, but the opposite had happened. He had been arrested at first, but his father had come and taken him out of his chains. He had even embraced him, and while that had been awkward, Edmund knew he had to play along in order to convince his father completely.
