The song "Jeg saler min ganger" ("I saddle my steed") was created by composer Natalie Holt for this episode. It was originally sung by Tom Hiddleston in an acapella form, but it didn't feel right to her so she asked the producers to have it redone with a chorus and musical instruments accompanying it.
This episode was inspired by the drama Before Sunrise (1995) and the bleak sci-fi thriller Children of Men (2006).
Initially, Sylvie was going to go on a rampage after breaking into the TVA in Lamentis (2021), killing almost everyone there before being stopped.
