Nero studied the picture, as well as everyone's reactions. He was still new to the concept of dimensions, and his dad had recently only promised him that he would not need to worry about dimensions until he was at least a Mystic, but if appearances were anything to go by, he was dead wrong.
Due to his largely lack of knowledge about dimensions, Nero did not have a large reaction to the appearance of new dimensions, though he was interested to learn that not all dimensions could be accessed from everywhere.
The others, however, were taken aback, as if their very understanding of reliant had been challenged. There were some who had no reaction at all, as if they already knew - Vanessa being one of them.
