Bianca met Amberly on the airplane to the palace in Angeles from the Selection. Amberly states that Bianca comes from one of Honduragua's neighboring provinces, which means that Bianca is most likely from the South (probably Panama, Bonita, Paloma, or Dominica.) She talked to her mother through letters during the Selection like the other girls, which means they may have been close.
Bianca was friends with Amberly and Madeline, usually sitting with them in the Women's Room. When Bianca told Amberly and Madeline about how Hendly, a former Selection participant, was "engaged", Bianca and Madeline were thrilled at the prospect of Hendly marrying a Two, as it meant they might marry "an actor" as opposed to someone with a Three's medical profession. Amberly was skeptical over "marrying someone you don't even know." Madeline and Bianca were comparing that to the Selection, expressing how they didn't know Prince Clarkson well.
Bianca talked about a gossip about Tia. She said that Tia was seemingly "smug" and mentioned Clarkson. Bianca felt that they should know if the rumor was true or not, while Amberly did not. When Queen Abby threw Tia out, she warned the rest of the girls, even slapping Amberly. When the Queen left, Amberly's face still had "her handprint" as pointed out by Bianca.
After Abby went on vacation, the threat to the Selected was diminished, so they talked and walked around as friends. They even traded some fashionable things. Bianca and Danica traded shoes, and Madeline searched the "jewelry box" in Bianca's room. Amberly and Danica talked about how Queen Abby was cruel to them. Danica realized that when it came to Prince Clarkson, Amberly was in love.
When Amberly was depressed, she recovered when Bianca was being funny and Amberly "laughed". Madeline was surprised, happy that her friend was back to her old joyous self.
Bianca seems to be outspoken as well as sweet and feisty. She also seems to be a close friend of Amberly's during her Selection along with Madeline.
