Millie is an aspiring journalist who writes about people and how they act. She can often come off as condescending, self-superior, and judgmental, but is generally social and kind. She has a noticeably very low opinion on her own generation. Millie is not a particularly strong player in the game, often being clumsy and unassertive. She forms an alliance with the much more athletic Priya and is trained by her to become stronger. The alliance ends up being very one-sided. Millie is usually carried by Priya throughout the challenges and rarely ever pulls her own weight, such as taking immunity for herself and quitting a challenge before it even started. However, near the end, Millie puts considerably more effort in the competition, something Priya takes notice of. It is later revealed that Millie's judgmental attitude is a result of her own insecurities. Due to having a lonely childhood, Millie has a very low opinion of herself and finds pointing out other people's flaws easier than thinking about her own. She also seems to struggle with social cues throughout the season. This explains some of her actions that end up upsetting Priya, such as taking immunity for herself after Priya refuses it and offers it to Millie instead. She initially became friends with Priya mostly so she could stay in the game longer for her research, even writing negatively about Priya and her parents behind her back. However, Millie grows to form a genuine bond with Priya and even decides to not to publish her findings, ultimately reconciling with her.
