Glob is ugly and imperfect and he was an outright POS at the start of his character history, but he tries. That's a good start to a highly relatable character right there, so it makes sense that he would catch on. All they have to do is keep letting him grow, keep using him. He was the best part of an issue that was filled (or left nearly empty, rather) with a very, very thin plot and characters that lack compelling motivation.
I've been pro Glob since Lemire.
Also, Nate Grey as a concept (kid from the future, alternate universe, clone of an ALREADY EXISTING kid from the future, Jott baby, messiah figure) is awful and should just be killed off unceremoniously. Stop making characters like this lol.
