What a lovely Introduction to Hattie! Echoing what others have said about the Characterization of 12, it's great! There is a lot to like here! The Setting is great. How it goes about its Story is pretty great. And the Art! Wow, that's quite very good Art, and it gets Capaldi Likeness right like no other. I especially like the Opening Pages, visually stunning is probably the best Word to describe it. The titular Twist works for me, even if I wish that ending was fleshed out a bit more. But I can look past that, since what we have here is pretty enjoyable, and it feels quite like Classic Who in places, which will always be a Plus for me!
