It was planned that Angel and Groo would find Kate Lockley as a working girl in the bordello they visit but Elisabeth Röhm was too busy appearing in Law & Order (1990) to fit in the cameo.
During Angel and Wesley's visit to the book store, a book with a red cover bearing a picture of a wolf is visible. This is the same book Wesley saw in Pylea, from which he determined that Wolfram & Hart, under a different name, was active in that dimension.
Lorne tells Angel "Fine Miss Garbo, Have it your way, be alone". This refers to Greta Garbo who led a private life of simplicity, never married, had no children, and lived alone as an adult.
Gunn gives the location of the tree where he and Fred are trapped as "near Plummer Park." This is a real park, located at 7377 Santa Monica Blvd, West Hollywood, CA 90046.
At the beginning of episode, Lorne smells the perfume of Angel's jacket and says he didn't have this smell the night before. This refers to previous episode Waiting in the Wings (2002) when Angel got magically attracted and started making out with Cordelia.
