Cassandra Did It
When authority figures, particularly incompetent ones make a bad screw-up, they're going to need a scapegoat to pin the blame on. In a related plot, the entirety of stage one pretty much consisted of our hero attempting to warn said authority figures of what was going on, only to be brushed aside as being irrelevant.
Well, hey, since this catastrophe was entirely unpredictable, there's only one logical explanation. Clearly, Cassandra initiated this whole devious plan, and the only way we have of stopping it is to get rid of Cassandra once and for all!
As idiotic as this kind of reasoning sounds, it is possible to use it in such a way that's not completely stupid. The Unintelligible may have shown up for the sole purpose of warning us about the catastrophe, but if we can't understand him, well, blaming him for the problem makes as much sense as anything else. Additionally, once Cassandra has been revealed as knowing something, the idea that she's an accomplice is plausible- although, since she's trying to warn you, treating her like a criminal is still pretty dumb. However, with certain subjects, their warning may be taken as a threat.
It may go without saying, but this shows up commonly in Real Life, particularly in regards to the War On Straw.
A possible outcome of a Cassandra Truth, as well as a potential fate of the Ignored Expert. Related to Shoot the Messenger.

- A variation of this occurs in Earl Cooper's backstory in the Batman: The Animated Series episode "The Mechanic". He was instrumental in blowing the lid off a scheme perpetrated by Global Motors. When he realized their newest model had a potential lethal safety defect that threatened lives, he was nearly killed by his employers in an attempt to silence him, but was saved by Batman. While he exposed said employers for the crooks they were, he would, for years afterward, be labeled a whistleblower, unjustly blacklisted by the industry, "unable to get a job as a grease monkey", as he put it. That is until, at the end of his rope, Batman appeared again, telling him simply: "I need a new car."
