Kitty calls him out for being "petty, heartless, and vain", and Nat goes "I'm not vain, just well turned out. Presentation's important!" I see his priorities have changed. Yeah, it's nice that Bart made fun of his "tent in a pocket" and "greasy waterfall hair", because Nat's sudden change to a bit fat douche would have made the book hard to read. People can't really relate to meanie protagonist.
