So I just noticed something odd on my third archive binge.
In
comic 1267, Hanners notes that she's just started knitting, just the very basics.
In
comic 2903, Hanners says that "last year's [scarf] was longer than this by now".
This suggests one of several things.
Either A) at least a year has passed between the two comics (as "by now" indicates that Hanners had started before that particular date the previous year), B) Hanners was joking about "last year's", or C) insert your own convoluted explanation here!
(I'm honestly not sure how time has passed in QC. I'll look into doing a day-tracker on my fourth archive binge in a few weeks.)
Seriously though, it probably doesn't mean anything (Jeph has stated that he doesn't really look back at his older work and that he's probably forgotten dozens of plot threads that he once had plans for), but I'm curious anyway.
