Originally, Amber is cold, spoiled and envious. When Sofia becomes a princess, Amber takes an immediate dislike to her. She acts mean to her and hates being called out on it. When the other children act friendly to Sofia, this makes Amber more jealous. Amber is also manipulative, able to trick James into humiliating Sofia. She likes looking pretty to other people, wearing the best dresses and tiaras. But after she rips her ball-gown and is too upset to attend Sofia's ball, and finds out Sofia made a mistake with a spell to be a better dancer that put everyone in the ballroom into an enchanted sleep, Amber apologizes to Sofia, who tells her she was happy to be getting a stepsister. Here, Amber corrects Sofia stating, "Sofia... we're sisters!" After making up, Amber and Sofia work together to undo the spell. This show that for all her faults, Amber isn't entirely a brat and now truly considers Sofia to be her sister, and she knows when to admit her mistakes. Also, while she does manipulate and ignore him, she appears to actually care and love James, judging by her reaction when James says that he likes Sofia better than her, which is the first time she is shown feeling truly depressed. Amber loves her family especially her father, King Roland and her twin brother, Prince James. As of now, she is becoming more responsible, kind, and a respective sister to Sofia by teaching her more about being a princess since she and Sofia became close friends. She is keeping Sofia out of harm's way as well. And while she is holding onto one of her old haughty, vain, and spoiled behavior, Amber is steadily improving as a princess and a person.
