This is such a brilliant episode, and one that only Voyager could have told, about the actual repercussions of representing something on a long journey that in this region of space doesn't actually exist. What I'm talking about is Janeway making a point to represent her ship being part of Starfleet, which in the Delta Quadrant (even to the Borg it's irrelevant, naturally), which by definition is supposed to denote a fleet (Enterprise touched on some of the pitfalls of this, too, while Kirk went out of his way to pretend just the opposite).
So a couple of opportunists start doing the obvious and perverting Voyager's legacy, and well, like I said, it's brilliant, a must-see for any fan of the series.
