Set a Stitch
The cast will eventually discover that when they have a challenge that makes no sense, it's likely a Stitch. Perhaps for them, perhaps for some other party (The Game has other contestants, you know.)
Pros:
This is a great B plot, especially with Pass for Normal. And you can literally make it anything.
Cons:
You can literally make it anything, and that's sometimes harder than specific requirements.
Fate Value: 4-6 Fate
Example:
"You will acquire a silver whiskey flask currently in the possession of Mr. Adlai Pickwick, of 713 Scanton Lane. You will then ensure that flask is in the casket of one Mr. Lewis Sinclair, a haberdasher of some note who passed away about an hour ago. The orderly course of history depends upon this..."
