What does "The plot thickens" mean?



Hello, Andreea!
When someone says "the plot thickens," they mean that a story or situation is becoming more complicated, mysterious, or interesting. It's like adding more layers to a story, making it more intriguing and challenging to unravel.
It's a way of expressing that things are getting more exciting, keeping everyone on their toes as the story unfolds.
I hope this answer was of help :)
