The boiling inside of Deans continue, and it was getting serious as time passes. It was about five minutes that Dean having trying to sense the light ray and finally able to get it.
…..
From his knowledge sea ZI was drawn to what was happening because bubbles were starting to show up in his knowledge sea, although it was not pronounced, it was unable to go unnoticed with ZI present there.
"What is happening" ZI said immediately using it felt Dean was just trying to heal himself was lost in some kind of epiphany at first it was troubling for him but since he did not need its help ZI felt it was not serious.
So it did not pay too much attention to it just allowing Dean to continue with what he was doing.
Applauding Dean for making the right choice not to ask for help from it, he had to figure some things, on his own.
