Meg and Calvin witness Charles Wallace being punished for deviating from the normal routine in the planet of Camazotz.
Here's why:
* Camazotz: This planet is ruled by the evil IT, which seeks to eliminate individuality and force everyone to conform to a single, rigid way of thinking.
* Charles Wallace: He is incredibly intelligent and sensitive, which makes him resistant to IT's influence.
* Punishment: When Charles Wallace tries to break free from the controlled environment, he is punished with an excruciatingly painful "treatment" that attempts to erase his individuality.
Let me know if you have any other questions!
