Keep up, and try to focus, okay?

From Brian in STL, successfully using the Suggest-a-CIDU form. His message starts from puzzlement, but arrives at a theory your CIDU editors are also happy with: It’s not entirely clear to me what’s going on. In a way, the first panels look like the preliminary sketches a cartoonist does. So is the coffee affecting him? Or is Jane now able to “focus” since she’s had coffee?
