Translation of the first page: Yes, our continuity is fucked! No, we're not going to explain it!
Yes, I get that it's a joke, but making fun of the fact that the continuity regarding things like Mary Jane's pregnancy simply can't be reconciled, and then, choosing to characterize that very same irreconcilability as literally maddening, is not the way to make the new status quo seem more appealing. Indeed, when you couple this page with the "Dallas" retcon of the marriage retcon in the Spider-Man comic strip - which Stan Lee and Roy Thomas claimed on-panel was the result of overwhelming reader demand for the restoration of the marriage, even though they'd always planned for the marriage retcon to be temporary in the comic strip - it's hard not to see this as a Take That to the current Marvel regime from Stan Lee.
Translation of the second page: HA HA HA PETER ALWAYS LOVED GWEN AND NOT MARY JANE, MARY JANE NEVER LOVED PETER, AND EVEN AFTER EVERYTHING ELSE HAS BEEN RETCONNED, "SINS PAST" IS STILL IN CONTINUITY!!! ISN'T IT FUNNY???
For as much as the current Marvel regime bemoans the fans, like me, who refuse to stop complaining about their retcons and editorial mandates, they really do go out of their way to antagonize us, even though there's no discernible benefit in doing so, since even a lot of supporters of the new status quo have rolled their eyes and expressed the desire to see Marvel move past this shit. Scabs do not heal if you keep picking at them.
