Klaus watched the weird faces both his father and the headmaster were making. So he asked, "What's happening? Why were you so concerned about this?"
The headmaster looked at his old friend before turning to Klaus.
He sighed and said, "Actually, when you went unconscious, most came to the conclusion that the third prince was behind this. Even the emperor thought so".
Klaus understood what happened and what the repercussions might have been if everyone thought that the prince was behind this, "Oh, did something happen?" he asked.
The headmaster shook his head, "Luckily nothing happened till now. The emperor placed the prince under house arrest until we knew what happened".
"Oh", though Klaus knew that the prince was not the reason behind the newest trouble he encountered, that doesn't mean that he would sympathise with him.
In his mind, the prince and Theon are at the bottom. He wouldn't care even if they died.
