As Daniel sits at the piano, he is actually playing the Graystone Theme that Bear McCreary has used throughout the serie's score.
In some of Zoe's flashbacks, scenes are used which did not make it to the final cut of the previous episode.
This episode was initially incorrectly advertised as the season finale when it was only the mid-season finale. Like the re-imagined Battlestar Galactica series, Caprica took a break after airing half of the series' episodes.
Jill Teed (Colonel Sasha Patel) also played Sergeant Hadrian in the re-imagined Battlestar Galactica series.

Title: "End of line"
"End of line" is a phrase that often punctuates many of the strange ramblings of the Hybrid in the re-imagines Battlestar Galactica series.
