The normal exam didn't consume much of Arno's energy because he had done a lot of preparation before the test.
He even finished the test paper early, but he didn't leave the exam room early; instead, he left with the other examinees.
According to the original plan, after the exam, Arno would swap identities with Harry—even after interrogating Harry last night, Arno still maintained this idea because he needed more time to monitor the development of the entire group led by Boston.
But he changed his mind at the last minute.
There were just too many uncertain factors, and considering Harry's current mental state, Arno couldn't be sure if Harry would suddenly lose control, not to mention Harry's hand was injured, which was also hard to explain... So, Arno planned to temporarily delay the identity swap.
