The song Adam is playing on the piano is "Rhapsody on a Theme by Paganini", by Sergei Rachmaninov.
The name Jordan Cross is a play on the metaphor "Crossing Jordan", the classic allusion of moving from this life to "The Hereafter".
Chloe says she is glad to play Woodward to Clark's Bernstein, a reference to the two Washington Post journalists whose tenacious investigation uncovered the Watergate scandal in 1972.
When Jordan bumps into Clark, the viewer is treated to a quick image of the classic Superman "S" symbol on a red cape, the same scene that appears on "Lois & Clark: The New Adventures of Superman" opening, while the camera flies through space.
Jordan has the power to see the future of people, specifically how they will die. Hereafter is also the name of an episode of Justice League, aired two months earlier, which is about Superman's supposed death when he is actually sent into the future.
