To Teige, Thomas had killed his lover. Therefore, if he was to take revenge on Thomas, he had to kill Thomas's lover.
So, Teige used the Brainwave Controller, hypnotized Anjiele, leading her to act on her jealousy, making her kill Thomas's fiancée Belennera.
However, because Teige was too dependent on his hypnotic controller, he overlooked Anjiele's unique personality traits, causing her to realize something was wrong.
In the struggle against Teige's control, Anjiele experienced many illusions, and to avoid hurting her friends, she harmed herself on her way to commit the murder.
Just like that, three cases that seemed like serial murders occurred.
Lex wanted to borrow Victor's lab for an assignment set by Shiller, but Thomas, who learned from his fiancée Belennera that she was being threatened, feared for her safety. Thus, he escaped from his prison cell in a hurry to find Belennera in the lab where she usually conducted her experiments and happened to meet Lex.
Batman, who had followed Thomas here, accidentally broke the storage device for frozen materials, turning Lex into a three-in-one villain. A fight ensued and nearly destroyed the entire lab.
Cobblepot, who came here intending to kill Lex, couldn't just stand by and watch. He adopted the most efficient method, which was to inform the teacher.
He found Victor sleeping in his dorm and had him come here. Victor, true to his moniker as Mr. Freeze, froze the two with two simple shots.
Shiller, who had just finished setting traps for the primary culprits, Hugo and Teige, wanted to ask Victor for help— or rather, he had reserved a spectator spot for his good friend Victor, intending to invite Victor to watch the fun.
However, when he called Victor's bedroom, Victor had already been summoned by Cobblepot, so the call did not get through.
Knowing Victor's habits, Shiller figured that if he was not in his bedroom, he must be in the lab. Thus, he also came here.
Thus, they all ended up gathering here.
After all this was said, there was only silence. Shiller sighed and said to Batman in a disappointed tone, "Bruce, how many times have I told you, is there a future in fighting all the time? Did you win the fight?"
Batman stood silently in place and assumed a serious posture, "Call me Batman."
Shiller turned to Lex and said, "And you, do you want to train yourself to Superman's level and then go punching him?"
"Have your proudly intelligent brains given up working?" Shiller looked around the devastated lab.
Batman looked at the patterns on the ceiling, and Lex looked at the cracks on the floor.
"Both of you have failed this assignment!" Shiller's last sentence finally broke their defenses: "And so have your final grades!"
Lex and Batman both turned to look at Shiller, who continued, "Breaking the rules, causing such trouble, and with such low grades, you are only a step away from being expelled. Do you realize that?"
Upon hearing this, Batman and Lex heaved a sigh of relief. Lex looked at Shiller and said, "Professor, I am very sorry, but I am willing to make up for it. I will a building... no, two of the most advanced research buildings, including all equipment and necessary experiment raw materials, for ten years..."
Batman sneered, "And the energy system and lighting system, permanently."
"Do you think this will sway me?" Shiller's expression remained unchanged. He said, "Even if this settles the trouble you have caused, what about the problem with your grades?"
After a pause, Shiller continued, "I assume both of you have had enough fists thrown. Now, it's time to test those genius brains of yours, to ensure they are not rusting."
"Batman, later, one of the ringleaders will enter your dream. I think, I don't need to tell you what to do, right?"
"Also..." Shiller looked into Batman's eyes, "There's another person taking part in this examination, his name is Clark. I think, you wouldn't want to lose to him."
Batman immediately narrowed his eyes, the corner of his mouth turned downward, revealing that classic expression.
After Batman left, Lex looked at Shiller and asked, "Professor, what about me? What am I being tested on? I think I can handle Clark's opponent too..."
Shiller, who was about to walk off, stopped and turned back. Looking into Lex's eyes, he said, "Lex Luther, we are the same kind of people..."
"So, your opponent, is me."
