The judge who nearly fights Candy Ferocity is Sol Pendavis (playing himself) who is the House Father to the House of Pendavis, of whom Kiki Pendavis is a nominee for Mother of the Year. The judge in red is Freddie Pendavis. Sol and Freddie both appeared in the documentary Paris Is Burning (1990) and serve as consultants on the show.
With the exception of House Evangelista, all the Houses in contention for Mother of the Year are real houses within the LGBTQ community of New York.
