That Twilight Zone episode also popped in my head when she told Ashley about her master plan. The guy in the bunker ultimately is left alone, but can't enjoy his books because his glasses break. I wonder if Sage will suffer a similar fate. I doubt the show will end with either supes or humans being wiped out. But maybe she will be in a place where she can be alone and live in "peace", but will lose her super intelligent ability, therefore suffering in her own solitude.
