We'll look a snapshot of a character in a book I finished... The Sin of Sloth, Elyse. A witch with the appearance of a little girl, who lived centuries believing she was the cause of the extermination of a Native American tribe, even until she joined The Sins in the modern day. She was convinced by her peer at the time that she caused them all to burn, even though her peer was the puppet master behind it all. She emotionally secluded herself as a result of this lie, separating her self from her own team, and at their eventual disbandment by the hero of heroes, Sun Keeper, she hid herself physically among the wreckage of the tribe she thought she destroyed. She was doused in pain and sadness, and because she never talked to the rest of the Sins, they all assumed they were the cause of her seclusion, and she started feeling guilty about this thought, and became even more secluded, until a tribe-decendant out for revenge captured her and trapped her.
As The Sins slowly found each other amidst a nationwide man hunt for them, they found her before the heroes of the National Hero Association could, and were able to free her from not only her physical prison, but her mental one. She came face-to-face with her peer and the woman who had captured her, and made her amends with both. Her sadness had plagued her for years, but at the behest of her team, she finally found her peace. She no longer kept the lie in the back of her mind.
