Answer:
What other characters say about each other.
Statements by a character about what they hate
Statement by a character about what kind of clothes they like.
Step-by-step explanation:
The author employs the technique of indirect characterization to reflect a character's true personality(indirect characterization) and thoughts through actions, speeches, appearance, etc. to the audience contrary to the direct characterization. The above statements would assist the readers to peep into the character's true personality and insight into their psyche(likes, dislikes, hates, loves, etc.). This aids the readers to form an opinion or perception about these characters and consequently, determines the meaning and the author's message more effectively.
