For example, you could mention:
* Direct characterization: The author explicitly states Fredo's traits or qualities.
* Indirect characterization: The author reveals Fredo's character through his actions, thoughts, words, or appearance.
* Dialogue: The author uses Fredo's words to reveal his personality.
* Setting: The author uses the environment to suggest something about Fredo's character.
* Symbolism: The author uses objects or events to represent Fredo's character.
