This is the third episode of SVU that actress Lisa Joyce has appeared in. She played the character Michelle Young in this episode, Allie Martell in Missing Pieces (2011), and Kristi McGarrett in Avatar (2007).
Michelle Young and her daughter are said to be pink clouding after they think that Young wasn't actually raped. Other episodes mentioning pink clouding include Girl Dishonored (2013) and No Good Reason (2017).
Rollins mentions she called her therapist for advice about what to say about Billie's parentage. Carisi later reveals that her therapist is still Dr. Alexis Hanover, who Rollins first met in The Darkest Journey Home (2019). Coincidentally, the detectives also have Michelle Young use the cognitive reenactment technique that Dr. Hanover taught the detectives and Benson used on Raegan James in that same episode.
The story that Michelle Young recounts is similar to the story of her rape by Brett Kavanaugh that Christine Blasey Ford recounted to Congress: the reactions of her prep-school friends trying to distance themselves from the victim, the victim being the only one who remembered the party at which she was assaulted, and her memory being triggered by the layout of the house in which the assault occurred, in particular.
