In a room filled with machines, beakers, chemicals, numerous small animals, and various plants, Johann was trying to move his arms but to no avail. After facing Fade in battle he immediately retreated to his secret lab. He had tried many different things to figure out what happened to his arms and why he could not move them.
After using various tests on his biological state he could not find any problem. Based on the results of all the tests his arms should be functioning normally. In the beginning, it was true that certain nerve points were struck which resulted in him being unable to move his hands, but that was already fixed, so then why was he still unable to move his hands? Knowing that his nerves, bones, and muscles weren't the problem he needed to look at it differently.
