I’m talking about a fan theory, that if true doesn’t drastically upend the fundamentals of the fiction it is set in.
Mine is that in the American Dad episode ‘Can I Be Frank With You’, that Snot’s uncle is actually just another Roger persona. He appears suddenly and conveniently to pitch a bizarre scheme, he loves hanging around with teen boys and doing drugs, and the very instant that the plan has a setback he kills himself out of sight of everyone else. That’s just Roger in a suit and glasses.
Edit: Ok, so, people are having trouble with the word “inconsequential”.
In the musical wicked which I suppose is canon and happens at the same time, Glenda reveals to Madame Morrible that the wicked witch of the west will probably show herself if her sister (the wicked witch of the east) is in danger. So Morrible summons the tornado to threaten the sister which coincidentally brings along Dorothy. Glenda secretly was good friends with Elphaba (WWotW) so wouldn’t have intentionally gotten her sister killed. There was a lot of politics and propaganda and stuff, but Glenda wasn’t really a villain, just a vain person who found it easier to support an autocracy. Someone who has read the books could probably explains it all, sorry if I’ve ruined your headcanon!
