Gannet Brooks had been romantically involved with Travis Mayweather prior to the launch of the NX class starship Enterprise. In an attempt to keep Mayweather from accepting a position aboard Enterprise, Gannet Brooks claimed that space exploration was the "last vestige of colonial impulse". Eventually, she and Mayweather made a mutual decision to end their relationship.
Gannet Brooks was present at one of the initial talks for the formation of the Coalition of Planets. When she met Ensign Mayweather at the ceremony, she claimed that she had been busy reporting news since the Xindi attack in 2153.
When Brooks stated that she wanted her relationship with Mayweather to continue, the Earth Starfleet officer was initially hesitant. However, Brooks commented that if she and Mayweather waited another four years to resume their relationship, they would have too much catching up to do. Mayweather agreed and Gannet Brooks soon joined the ensign aboard Enterprise, claiming that she had been assigned to do a news story about the starship. The report would include an insight into the missions which the crew were assigned, their life in space and the perils they met there.
Gannet Brooks interviewed Ensign Mayweather, who gave her a guided tour of some locations aboard Enterprise, including the launch bay and the interior of a shuttlepod. She revealed that she had learned that one of the starship's shuttlepods had penetrated a sphere in the Delphic Expanse and commented that the shuttlepods were beautiful.
In shuttlepod one, Gannet Brooks revealed that she was still attracted to Travis Mayweather when she began to kiss him. After the couple spent a long time in the shuttlepod, they returned to Travis Mayweather's quarters. There, Brooks commented that she would never "settle down", although she would not be adverse to experiencing a serious relationship under the right conditions.
Suspected Terra Prime involvement
The crew of Enterprise later discovered that Gannet Brooks had reconfigured her universal translator at the conference on Earth to record messages from all the other translators and had been spying on the delegates there. Ensign Hoshi Sato claimed that Brooks had accidentally triggered an identification protocol in the network, which Sato had tracked back to the source. Most of the Starfleet officers suspected that Gannet Brooks was a member of the xenophobic organization Terra Prime. However, Ensign Mayweather believed that Brooks may have simply been doing undercover research for a news report.
Captain Jonathan Archer argued that Brooks had recently made several frequent visits to Orpheus Mining Colony on Luna, the headquarters of Terra Prime. Brooks claimed that she had been assigned there by her news agency and knew nothing about two officers from Enterprise who had gone missing on Luna.
Realising her predicament, Brooks demanded to speak with counsel, shortly before Captain Archer impatiently accepted her appeal and ordered her arrest.
In Enterprise's brig, Brooks requested to speak with Travis Mayweather. When the ensign arrived, she complained that she had not yet spoken to her lawyer. She also revealed that she was actually working for Starfleet Intelligence, not Terra Prime. Ensign Mayweather found her story hard to accept, however. He believed that Brooks would be able to quickly arrange her own release, if she were being employed by Starfleet Intelligence. In an attempt to explain why she had not already done so, Brooks replied that she was that a Terra Prime agent could possibly be operating on board Enterprise. Her own identity would be compromised if she were to attempt to contact the head of her division.
Mayweather warned Brooks that he would inform Captain Archer of her true identity. However, she and Mayweather speculated that the captain would probably not believe Brooks' story.
Gannet Brooks knew that Captain Archer was planning to find the leader of Terra Prime, John Frederick Paxton, on Mars. Brooks worried that if a Terra Prime agent was working aboard Enterprise, Paxton may have already prepared for the arrival of the Starfleet officers.
Mayweather refused to accept Brooks' story and continued with the mission without telling any of the other officers about her claim.
Shortly thereafter, Paxton was arrested and the Terra Prime spy aboard Enterprise, Ensign Masaro, later committed suicide. Gannet Brooks was released from imprisonment and learned that peace conferences were continuing on Earth. She believed that, due to the work of Ensign Mayweather and others, the Coalition of Planets would eventually be formed. Mayweather agreed with her that, like him, Brooks had just being doing her job. She suggested that she and Mayweather should learn to "get along" like the Vulcans and Andorians, two members of the potential Coalition of Planets who were renowned for their discordant relationship. Mayweather commented that he and Brooks had much to discuss and accompanied her back to Earth in a shuttlepod.
Gannet Brooks' surname was not mentioned in canon Star Trek and is taken from script sources, where the character is described as "an attractive woman in her mid-20's". Gannet Brooks was played by Johanna Watts.
