-> ''Why, by the way? Is it a soup metaphor?''
-->-- Gustave H., ''Film/TheGrandBudapestHotel''

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.

* One of the chapters in ''Literature/ThePhoenixGuards'' by Steven Brust is titled "[[InWhichATropeIsDescribed In Which]] [[LongTitle The Plot, Behaving In Much The Same Manner As A Soup To Which Cornstarch Has Been Added, Begins, At Last, To Thicken]]."
* A chapter heading in ''Discworld/MakingMoney'' refers to it, but is "the ''pot'' thickens".

* One of the ''Literature/EnchantedForestChronicles'' books has a chapter titled "[[InWhichATropeIsDescribed In Which The Plot Thickens]]", which is followed shortly thereafter by one titled "In Which The Plot Positively Curdles".
