Thanks, all. I think I will side-car the show with the books now. Why not?
Since I did watch a lot of S1, I picture Holden, Amos, Alex, Naomi, and Avasalara (I love this actor so much), and Miller as the actors who portrayed them. But, like, Bobbi and Prax from Caliban, I just have my own mind's creation. It'll be interesting to see how they compare... assuming mostly the same characters are in both.
