I’ll go first. Mine is the instant knockout drug. Like Dexter’s intramuscular injection that causes someone to immediately lose consciousness. Or in the movie Split where there’s the aerosol spray in your face that makes you instantly unconscious. Or pretty much any time someone uses chloroform.

For all the faults of the final seasons of Game of Thrones, I appreciated that this was the consistent message in the novels and show: beware powerful men and women, and those who aspire to be, because your interests are not their interests. The government formed at the end of the show was basically the least-worst option available in a feudal society.
