- A familiar, two-note motif plays when Ana-Lucia visits Eko in his dream. The same music played when Boone appeared in Locke’s dream in Deus Ex Machina. Add that to the list of parallels!
- Eko’s motif and Locke’s theme play together as they open the Pearl hatch… together.
- A new theme for Eko and the afterlife is introduced in this episode. It’s heard again in Three Minutes, when Eko talks to Michael about Hell.
- A simple new motif accompanies the scene where Eko and Locke explore the Pearl Station. The same, one-noted beat will make an extended appearance in Through The Looking Glass (“Patchy At Best”), which in turn will be heard again in Meet Kevin Johnson.
