From the very beginning, I had always intended for Roll's character to be much different from her canon good-girl image. Rather than being a polite, soft-spoken maiden like her video game character might be, in the comic she's a foul-mouthed little spitfire. In addition to having her swear like a sailor and enjoy blasting things, early on I was also considering making her a total slut as well. In fact, in this comic, I was originally going to casually insinuate that she had had sex with the Author.
Two things stopped me from going ahead with this idea. First, with all of the other questionable things I've done with Capcom's beloved characters, I felt turning Roll into a whore might be crossing a line. Second, and perhaps more importantly, I'm not sure I really like the idea of the comic personification of myself having sex with an underage robot.
Also in this comic is a reference to the "real" comic starting soon. I'm sure I had plans to actually start the hand-drawn comic again soon, so Proto Man's line would be a joke about how you can't believe a drunk, only to have it turn out to be true when the "real" comic started shortly, but then those plans fizzled as well. Which makes his line more a joke at my expense about how you can never trust what I say. Ever.
