Answer:
It can be revealed through characters or events.
Step-by-step explanation:
An implied theme refers to a central message, life lesson or moral that a story or other literary work holds about a topic and that is not directly stated by the author and rarely is it explicitly revealed by a character. Instead, it is a message that is usually revealed through characters and the plot or events of a story, and the reader has to find it out.
Take the novel To Kill a Mockingbird by Harper Lee, for example, who has several implied themes, one of them is “Courage is about doing what's right whether you win or lose” which can be revealed through Atticus's determination to face down the racism of the town, regardless of the high probabilities of him losing.
