Ferreira’s character Kat is in the lineage of 1990s cult favourites such as MTV’s titular Daria or Enid and Rebecca from Ghost World; in Ferreira’s words, ‘A really flawed, bitchy, inherently cool character, all these monotone, cutting deep one-liners, very tough exterior, I don’t care about anything kind of vibe, but so much heart.’ At East Highland High School (‘or Euphoria High, as the kids say!’), Kat is a sardonic teenager, insecure about her body image, who feels unattractive and unappreciated by her peers. A potentially humiliating event in the pilot episode of the show sets Kat up for a more confident, sexual side of her to emerge as an online camgirl called KittenKween. It’s a twisted twist on the makeover scene trope. ‘At first Kat was supposed to be this quote unquote unattractive girl,’ says Ferreira, who was instrumental in developing the character alongside Euphoria’s creator and writer Sam Levinson. ‘So I made sure that it wasn’t going to be the makeover scene where she takes off her glasses and all of a sudden — wow! hot! I wanted the makeover scene to be… kind of worse?’ she laughs.
