At the first, I like Sierra's character. She's smart, know-it-all, and struggling to be confident in her own skin. But then, she began to become annoying. She literally catfished a guy, sexually harassed him by kissing him without him knowing it was her, and then 'revenged' on someone who is nothing but helpful to her. Sierra is a mean girl, and Veronica is a good person.
