Angst? What Angst?: The village takes the whole "We're just holograms" thing in pretty good stride.
Nested Story Reveal: Subverted. Rurigan argues that the holographic simulation he's created should not be restarted once everyone has learned the truth about it, especially since he's about to die anyway. Odo and Dax counter the argument by suggesting that even simulated lives can in some sense be real and not mere fiction, so in the end they bring back the simulation, and presumably it keeps on running long after Rurigan's death.
