So, we have a story arc on our hands! Wonder whether it will ever get resolved?
I added a bit of texture to the background, so now it looks more paper-y. I hope you like it. For those who are wondering how to do it, render differential clouds in GIMP on a separate layer then use this layer as a bump map. You need to tweak some parameters so that it looks good and not too bumpy.
Also, I just realized that comic 6 means that Blub Cheese now passes the Bechdel Test: it has 2 female characters talking about something other than a man! And it wasn't even intentional.
