This Comic's Cast:

This is a classic "upping the ante" maneuver. Also known as "It Can Only Get Worse" (I believe there's actually a trope more or less called that). Whenever a character screws something up, there's always the chance that the situation can get much worse before it ever gets better (if at all).
Does make you wonder what Wilbur was supposed to do. Could be an interesting alternate reality...
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
