Raylan (Timothy Olyphant) says the photo of 19th-century marshals behind his desk makes him wonder if he should grow a mustache. Olyphant famously sported a mustache while playing Seth Bullock, a U.S. marshal and sheriff, in Deadwood (2004) and Deadwood: The Movie (2019).
Raylan drives Winona to a meet with her lawyer (Mandy McMillian) and Gary's lawyer (Sean Smith) on the corner of Cameron and Chase, a reference to fellow Fox show House (2004). McMillian and Smith both guest starred on "House," as did Joseph Lyle Taylor (Doyle Bennett).
