Wayne shows up
Another aspect of the Mistborn books is the humor. I plan the humor in each of my novels specifically. In Warbreaker, the humor is all about wordplay and lofty back-and-forths. In the Alcatraz books, it's about being audacious, whimsical, and . . . well, a little insane. In The Way of Kings, it's more character-specific, certain characters engaging in different types of humor to fit the scene.
The Mistborn books have always employed a type of humor I'll call grim banter. Friends who know each other making jokes back and forth amid sometimes terrible situations. There's usually an edge to the banter, much how Kelsier would speak in the original trilogy. I wanted to maintain that feel, and so for this series to work, it needed to be founded on at least two characters who knew one another well and who were comfortable with insulting one another in the name of levity.
It was actually hard not to get to Wayne sooner in the book—even though this is only chapter two, he's a big part of the heart and soul of this story. I wanted to get him in quickly, as quickly as possible. This was the right place, I'm confident—he'd have distracted from Lessie in the prologue.
I'm pleased with how he turned out, by the way. He's vibrant enough as a person, with a good soul and a lot of quirks, that he quite often steals the show. That was a balance I had to work on in the book to make sure he didn't steal it too much. (Or, at least, too often.)
