When Riker and Ro are flying the Maquis ship, about to "discover" the Enterprise hiding in the nebula, a shot of the instrument panel shows a line drawing of a Galaxy-class star ship, indicating this is a reuse of an instrument panel normally found on the Enterprise.
At the beginning of the episode, Picard asks Ro to come to the bridge.
While she is talking with Geordi, Beverly and Deanna, the shortest route to go to the bridge would be the door behind her.
When Riker and Ro Laren are in the shuttle craft, they appeared to be stationery as the stars outside the window weren't moving.
Ro says she was sent to the stockade on Jaros II after being court-martialed. This is not to be confused with Garon II, where the incident that got her the court martial occurred, as mentioned in Ensign Ro (1991).
Picard tells Ro that two years ago, Starfleet would never have considered sending her on the mission at hand. She later tells the Maquis that she was released from prison three years ago because Starfleet wanted her to work for them in Bajoran matters. What Picard means here is that Ro would not have been chosen for this type of mission shortly after being reinstated by Starfleet, obviously because of its much more sensitive nature. In the meantime, however, she must have gained a lot of credit with Starfleet, which Picard suggests as well.
In the opening battle with the Maquis, when the Enterprise disperses two of the ships with phaser fire, space appears to be shaking. This, however, seems to be a common effect whenever explosions occur, in order to simulate the shock wave.
When Capt. Picard is talking to Lt. Ro in the bar, he tells her that there are only going to be six ships in the convoy and they could cut that number down if they had to. However, later, when Data is talking Capt. Picard, he says, "This is the convoy," and the camera changes to view the Long Range Scan 0128 and there thirteen objects with labels, nine white and four blue moving on the screen.
Riker tells Picard he never thought about shooting on his own people to protect Cardassians.
In The Wounded (1991) Picard also threatens to destroy the USS Phoenix.
