Deepskyfrontier and Sgeo have informed me that the date of the recent wedding is exactly ten years after Arcadia's first appearance, an anniversary that was revealed to be the planned wedding date back in 2005. This self-imposed deadline may partly explain the reason for the story arc coming to the point so quickly. The fact that it happened to fall on a Sunday is surely a small insight into how much of a well-oiled machine Superosity truly is.
It also turns out that the nondescript person to the far right of the wedding comic's first panel is Deepskyfrontier himself. The jerk no doubt took Corey Feldman's place, leaving poor Corey to scrounge up salted rust flakes for dinner instead of feasting on delicious wedding cake. Alan appears to fancy Deepskyfrontier however, so it may turn out for the best. With luck there may be more Superosity wedding bells ringing in 9 years and 352 days.
Sgeo notes that the date was set during the same storyline that revealed the truth of the nano-robotic hearts. Given the hooplah immediately following, and the fact that we are yet to see how Boardy ruins Chris' wedding (not to mention which Boardy is to ruin Chris' wedding), this may be a note worth noting.
