Daniel Dae Kim (Max Lee) and Kimee Balmilero (Jenny) both worked together on the television show Hawaii Five-0 as Lt. Chin Ho Kelly and Dr. Noelani Chuna. These 2 shows both filmed in Hawaii.
During the episode, Charles spends most of the episode helping Dr. Lee create his sizzle reel for "The Bachelorette." This is a nod to the fact that Jeffrey Bowyer-Chapman, who plays Charles, spent three years on the show UnReal playing a segment producer on a reality dating show based on the Bachelor/Bachelorette series.
