Picard tells Ro the convoy will have six ships, but when we see it, it has 12 ships.
Ro's nose design is different then in previous episodes (it has two less ridges).
This episode contradicts the events of "Journey's End." There they say that any Federation member staying in the disputed territory is on their own and the Federation will have nothing to do with them. Here the Federation has to deal with folks who stayed in the disputed territory.
Nechayev initially says that Starfleet doesn't have reliable intelligence on the Maquis, but later Picard tells Ro that he has intelligence saying the Maquis are eager to strike.
This is the final of appearance of Admiral Alynna Nechayev (Natalija Nogulich) on Star Trek: The Next Generation. She later would appear in another episode of Star Trek: Deep Space Nine.
The idea that Ro's instructor is Chakotay is actually stated as a fact on the official Star Trek website.
This episode was the sequel to the Deep Space Nine episode "The Maquis".
