Well, bottom line is, no RP (or any comedic series for that matter) can escape the looming terror that is a dark, serious arc or situation. No matter how hard you try to keep it lighthearted and silly, it's going to happen, and the only way to get that lighthearted silliness back is to finish the situation or arc that started it and move on with only distant memories popping up whenever others feel like bringing it up.
That was pretty much the one thing Busy World did right, as bad and cluttered as the RP had become. At one point, the RP stopped being silly and had about 3+ pages of serious, heat-wrenching moments that almost ended with both worlds being controlled by two overlords. But once Dragon Sky cleared it up, it went back to its usual silly nature.
