This episode continues the tradition of Crowleys drinks having little devil pitchforks in them, shown at the beginning when he and Castiel are in a bar first talking to Dean and Sam.
While playing Words With Friends with Mary after playing the word "TWERKING" Dean recieves the letters "LURIFEC" - rearranged they spell "LUCIFER". He also uses a devil emoji when messaging her.
At 11:30mins they show the Hollywood Star Walk and the star for "Milt and Bill Larsen". They are the brothers who transformed an old Hollywood mansion into the Magic Castle. The castle is the home of the Academy of Magical Arts, a private club with about 2,500 members. Alumni include David Copperfield and Siegfried & Roy.
The montage of Beverly Hills (music and b-roll images) and the music during transitions is an ode to the TV series Beverly Hills, 90210.
"The seeds of a ripe dragon fruit drizzled with exactly one ounce of acacia honey." The seeds of a dragon fruit are minute, grain of salt size. One ounce (fluid volune) is two tablespoons. This specified breakfast would be about the size of a single chicken nugget, and slightly less nutritious.
