Butters is seen helping her by filtering out negative comments she receives, in addition to doing so for Cartman. She also sings in the song "In My Safe Space". She is later seen at the end of the episode, taking part in Randy's final advertisement where he reveals that now homeless children in other countries are filtering out the negative comments of celebrities like her.
Demi's appearance here seems to be taken from her initial appearance back when she was on the Disney Channel. She has long, black hair and light skin with no noticeable flaws. She is dressed in a black possibly dominatrix-inspired outfit and her hair is styled in a way that most of it falls down the left side of her head like Bebe Stevens. She has pink mascara spots on her cheeks and wears eyeliner.
Demi's personality seems to be that of a typical teenager, caring about what others think to the point where she was willing to ask a fourth-grader to filter out her social media accounts just so she could only get positive comments.
