Let's discuss Chucky's mental state.
Tell us about Chucky's mental state, was it multi-level? You suggest Chucky's boolean condition was stuck, like Chuck's Chocks.
Conciousness is an effect of evolved organisims, which brings salt to the wound of existence as The Toba Event exonerated some forms from Cheap Booze and the 20-20 vision of Mad Dogs. I propose proof of non-existence of evolutionary development beyond humanoid form is difficult in that the wipeout effected by The Toba Event would not be proveably selective at allowing only two haplogroup ( from "ἁπλο-" Greek haplo-: simple or single + "group" ) to continue beyond that cataclysmic eon.
Perhaps Chucky is just morose and has special skills or powers, I know I do. They are nothing special at all and are the natural state.
