This episode contains the only instance of Ro being (correctly and intentionally) referred to by her given name - when Captain Picard meets her at the bar and asks "Laren, what is going on?"
The only time the Maquis appear in Star Trek: The Next Generation (1987). We get to see the DMZ too, after it was established in Star Trek: Deep Space Nine (1993) and in Journey's End (1994).
Macias was named after a freedom fighter in Cuba's War of Independence from Spain in the late 19th century.
The penultimate episode of the show. To mark the occasion, TV Guide presented a special retrospective issue devoted to the long-running show, which had been on the air for seven years and was now about to end.
We see a Native American on one of the Maquis ships. It is possible he is from Dorvan V, the colony that Starfleet handed over to the Cardassians in Journey's End (1994). Which may be why he joined the Maquis.
