The famous Bob Dylan song 'All Along the Watchtower' (also famously covered by Jimi Hendrix) was the source for the lines of some of the main characters near the end of the episode: "There must be some way out of here, said the joker to the thief / There's too much confusion, I can't get no relief." Also "No reason to get excited," as spoken by Anders.
This is the first episode of the series to feature background music in which English-language lyrics ("All Along the Watchtower") are used.

Bear McCreary's newly composed theme underlying the lyrics of "All Along the Watchtower" is repeated throughout using electric sitar, harmoniums, duduk, yialli tanbur and electric violin. At the end, Steve Bartek plays the theme on an electric guitar, tuned down to C# minor. (The lowest string on a guitar -- in terms of pitch -- is normally tuned to an E note.)
For the second time in a row, the usual opening title sequence was removed and the names of the main cast members appeared on screen during the teaser. The number of survivors in the fleet was also absent.
