"Journey Into Night", which is the episode's title, is the name of Dr. Ford's final game-changing new narrative, which was introduced on the last scene of season 1.
The WB logo card at the end of the episode has the usual theme ("As Time Goes By") played over it, but arranged for an upright piano to sound a bit more like a Western saloon.
At approx 31 min in visual effects give The Man In Black / William (Ed Harris) the same single dot sparkle eyes that Yul Brynner had in the original Westworld.
Though difficult to see except in UltraHD, the gray catamaran carrying the Delos extraction team to the beachhead has the company logo on it.
