The Advisor tried to persuade the king on his point.
"Sir, you're getting emotional due to our worst history. This matter is apart from that. Let's send him for micro-checking".
The king couldn't behave his guests like that. Microchecking was a stressful process in which one was hung upside down and tortured with high-intensity rays to check if he was normal or not.
It was used for mental aliens to analyze their bodies before sending them to the alien's mental house.
When the Advisor thought the king wouldn't be convinced, he changed his polite tone to harshly.
"My king, I think you have believed that he's your grandson, and that's why you're sympathizing with him. Otherwise, if any other alien were in his place, you wouldn't forget him".
It didn't matter. King was so polite, but he didn't allow anyone to disrespect him. He became angry and was about to leave from there when the Advisor asked for an excuse from him.
