The guards quickly unhanded the spy, and then pushed him in front of the emperor.
They obviously weren't happy with the fact that the emperor had let the intruder go so easily. They were rough handling him, pushing him around and even whispering insults in his ears. It was a little dramatic, but that was how the guards were.
They were looking forward to killing the intruder.
That was their only joy in their very long and tedious life. The feeling of watching heads roll was unparalleled. It brought them great relief after a long day of work.
As for the spy, he couldn't be bothered with what the guards were doing. A great honor was coming his way. As long as they didn't hurt him physically, he should be fine. He was confident that he would get away with practically anything he said, as long as he broke the news to the emperor.
This was multiple pieces of fantastical news.
