When you’re a hologram in a hologram in a hologram having a holo-dream, it can be hard to tell what’s really virtually real. In this episode of Voyager, the ship’s holographic medical program boots up only to discover that things have happened, only to discover they haven’t. A Kazon is on a rampage, but he’s not. A guy shows up, but he doesn’t. Tough decisions have to be made, but they don’t. Nothing is at stake and it didn’t even happen, but at least it didn’t even happen to sort of an interesting character.
