Cool with the sunglasses, no meaningful eye-contact with the sun-ray stimuli, as it provides truth, opposite to the purpose of an alter ego. Nick knows that the ego is the separation from the soul. Alter ego being the branch spiral of every ego, from the soul. They are the soldiers of the soul, but sometimes they go rogue. He only knows that because he has met all the other alter egos and together they perform. When one falls too deeply into the purposes of the alter egos, he may become too distant with the soul, eventually losing contact and being unable to return to it.
