Greenwalt discusses how Cordelia "is sort of forced to become a deeper character" when she starts to receive the visions of the suffering and helpless, "She's sort of living with one foot in the world of 'I want to be an actress' and with another foot in the world of 'I want to save and help people, and I have a deeper purpose and mission.'" Greenwalt felt that this development allowed Cordelia to develop from a "vainglorious high schooler to someone who's almost like a superhero"; this also provided Carpenter with the opportunity to stretch her potential as an actress. From the tenth episode, "Parting Gifts", Cordelia begins to actively function as a supernatural character in the series while the introduction of Wesley also contributes some added comic relief to the series. It is from this episode Cordelia is also forced to mature as she mourns the death of Doyle, whose visions serve as a painful reminder of him. The first-season finale saw Cordelia's visions inflict all the suffering of the human world upon her, and to effectively act this, Carpenter's acting coach showed her pictures of real human pain as motivation. The scene took over eight hours to film, and Carpenter was relieved when it was over. The experience saw Cordelia further resolve to help those in need, stating "I saw the world and there's so much pain. We have to help them." Carpenter explains, "Through the suffering of the world, and through her own experiences, she discovers what's important in life."
