I had fun illustrating this one. I should try to make that a goal, rather than just a possibility, more often. I'm not actually sure whether it takes more or less time to make a comic when I indulge myself art-wise given how my mind wanders when I don't.
Sincerely, a visually simple scene with dialogue I love can be more intimidating than someone visually demanding by virtue of creation process tedium. I think it's one reason why there are so many fantasy panels in EGS.
Well, that, and early seasons of The Simpsons were heavily influential on me.
Anyhoo, I think the comic implies this well enough, but in case I'm mistaken, "Jack" is considering the possibility that someone's real world opinion of the real Arthur resulted in NPC Arthur being cast as the villain.
Sort of like if you thought someone was a clown, and then had a dream in which they were literally a clown (this example does not work if they are actually a clown by trade).
