I think you're right. The Washington Post article backs this up,“Several years ago, when Stephan did one of his strips that mocked his own drawing ability and mentioned my strip in comparison, I thought it might be funny for me to ghost ‘Pearls’ sometime, just to flip it all on its head,” the goateed Watterson tells me, offering a clear indication that he still follows the funnies. “It was just a silly idea, and I didn’t know Stephan, so I never pursued it, and years went by.”
