The previous comic was posted so late on a Friday that I temporarily merged that comic with today's comic when Today's comic was originally posted. That may have been overkill, but at the time, the date for the comic wasn't anywhere on the page (note to self: get that fixed so it's truly past tense), and I never expect people to visit on the weekend.
In short: I wanted to make sure nobody missed Friday's comic ^^;
This comic introduces an additional complication which I was somewhat hesitant about introducting because of it's "additional complication" status and some people already being confused. Then I decided to do it anyway because it's cool and I wanted to. Besides, I'm encouraging the flexing of deductive reasoning muscles.
For now, I'm going to say "it's a magic simulation. A LOT could be possible".
