Opening up about taking on the role, Sweeney told the Hollywood Reporter, "I definitely felt the weight of the importance of every word and every moment that was shared between these characters, because Reality had lived a life before this." "We show this very incredible snapshot of a moment and from my conversations with Reality, I filled it in. So when you meet this character on screen, you meet Reality." The White Lotus star added, "You just meet her for this one day in her life, but you can get a sense of who she is, where she came from, what's going on in her mind as she's trying to figure out what to say to these FBI agents."
