You could say that the addition of grey to the black and white was a foreshadowing of how the series goes as more and more of each side show that they are not fully one thing or the other and it resembles more of a political system than the good vs evil it started out as. Of course, Max is at the center of it all and stirring things up. I really enjoyed the addition of myth til and the take on what that would be. Excited to see how this evolves from here.
