Trish is first introduced as a spoiled, selfish girl; this is later revealed to be a way to hide her insecurities, although her self-doubt is still apparent in instances such as expressing her nervousness to Bucciarati whether she and her father would get along or not. Over the course of the time she spends with the group, a deeply loyal, determined side of her is revealed. When she discovers her Stand Spice Girl with the help of Giorno Giovanna, she comes to terms with her own power to defend herself and her new friends. She is also seen lightheartedly teasing and joking around with Guido Mista towards the end once she is comfortable around him, implying that this is her true nature.
