StockPhrase often said after a turning point in the {{plot}}.

It usually refers to [[{{Plot}} things]] becoming [[GambitPileup overly complex]] or mysterious. Today this term is often PlayedForLaughs. Coined in the 17th century, it originally described the plot of a play that was overly intricate, and by the late 1800s it was used for [[SherlockHolmes increasingly complex mysteries in detective stories]].

The phrase is sometimes parodied as "The plot sickens". You may also hear "the plot thins" - usually uttered after a major AntiClimax.
