The fake Robin was disappointed because his plans had not worked. With the agent standing there, how could he access the WC and look for a way of escape?
Also, he expected that there would be some kind of entrance for them to use to a washroom, not what was happening in front of him.
"You are watching," he said to the agent.
If the agent could face the other way, the fake Robin could analyze the WC to check if there was a way around using it to escape.
The agent carried a personal grudge towards the fake Robin, wondering the reason why Mr. Jewel was even wasting time in keeping the man alive when he should be dead.
"You are already dead meat. Pee now or it goes back," he replied in annoyance, ready to press the blue button again as he continued,
"If you pee inside your glass cubicle, you will live with the smell. As for food, Mr. Jewel said that he isn't responsible for you," the agent let out a sinister smile.
