Brooks was among the crewmembers who were transported onto the Caretaker's array shortly after the Voyager was lost in the Delta Quadrant. Alongside another officer, she scanned the region at captain's orders. (VOY: "Caretaker")
In 2372, she visited the mess hall where she witnessed the "food fight" between Tom Paris and Neelix. She stood next to William McKenzie, holding a tray with food, when Paris and Neelix were called by Captain Janeway. Later, reading a PADD, she walked in a corridor when Kes tried to talk to Neelix about his fight with Paris. (VOY: "Parturition")
She was talking to Kashimuro Nozawa in the mess hall when Neelix gratulated Tuvok to his Kal Rekk. Later, she was among the Starfleet officers in Chez Sandríne who participated in the betting pool led by Tom Paris. She was also present when Commander Chakotay stopped the betting pool. (VOY: "Meld")
She greeted The Doctor while she passed sickbay. The Doctor, who was at the time malfunctioning, began to follow Brooks as she made her way to the turbolift. Unknown to her at the time, as Brooks traveled aboard the turbolift to deck 10, The Doctor stood behind her plotting his move of malcontent against her. Fortunately, Brooks was saved when Tom Paris entered the turbolift and unknowingly interrupted The Doctor's plans. (VOY: "Darkling")
Brooks visited the Paxau Resort when Kes experienced one of her timeshifts and witnessed the Krenim attack on Voyager. Later, in the normal timeline, she attended the party for Kes at the Paxau Resort holoprogram. (VOY: "Before and After")
In an alternate timeline, Brooks was the room mate of Seven of Nine and greeted Seven when she passed her in a corridor. Tuvok, unable to see Brooks because of his blindness, asked Seven if this was a friend of hers but Seven told him that Brooks was untidy and left her belongings everywhere in the room. (VOY: "Year of Hell")
Brooks was in Astrometrics in 2377 to watch the positions of the Antarian Trans-stellar Rally racers with excitement evident. She stood next to Seven of Nine and in front of Fitzpatrick. (VOY: "Drive")
She was among the crewmembers in the mess hall when Neelix handed out isolinear chips with different numbers to every crewmember which allowed them to have free call time to people on Earth including their families and friends. (VOY: "Author, Author")
In 2378, Brooks attended the First Contact Day party in the mess hall and stood later in the corridor with much of the rest of the crew to bid farewell to Neelix when he left the starship for good. (VOY: "Homestead")

Ensign Brooks was portrayed by Sue Henley throughout the run of Star Trek: Voyager. Henley was also the main stand-in for Kathryn Janeway actress Kate Mulgrew and previously appeared as a command officer in the second and third season of Star Trek: Deep Space Nine.
Henley was credited as "Ensign" in the end credits of the episode "Darkling". Later, in "Year of Hell", she was credited as "Ensign Brooks" and had one word of dialogue, "Seven". The call sheet for this day of filming, Thursday 14 August 1997, is also listing her as "Ensign Brooks" with a makeup call at 8:00 am and a set call at 10:00 am. Because Henley filmed her scene on Paramount Stage 9 and had to prepare for this appearance, fellow stand-in Susan Lewis worked as stand-in for Mulgrew that day.
According to an interview with Sue Henley, she did little background work on the first season because of her strong likeness to Kate Mulgrew. Occasionally, she wore a wig, which she described as a "hideous black dead-rat-looking wig."
