While engaging them in hand-to-hand combat, Thorn complained that she had the situation under control. Pereira then approached and told them to relax, using her distraction as an opportunity to disarm one of them. Thorn confronted the men who drew their guns on her. They both followed the man to a vacant lot and learned he was trying to sell weapons as well as a funeral mask that had been stolen from one of Pereira's favorite museums. Thorn disregarded the comment and ran after the man with the brief case. Pereira told her to ignore them as they were off duty.

While visiting the Parthenon, Thorn noticed two suspicious men exchanging a brief case. Upon returning to Greece, Pereira accompanied Thorn on a trip to Athens to go sight seeing. While the training was intense, she and Slege enjoyed their time at the farm and the beauty of its surrounding landscape. A short time later, Pereira and Seamus "Sledge" Cowden were invited by Thorn to train at her family farm in Ireland. Thorn accepted Pereira's offer and was recruited into Rainbow and placed on Pereira's team for the Invitational. After barely completing it, she asked the course's architect, Brianna "Thorn" Skehan, if she wanted a job. Pereira later heard of the Garda ERU's new grueling obstacle course and tried it out for herself. She also started a relationship with a woman named Camila Amoreco. Towards the end of 2021, Pereira was made Team Captain for the upcoming Invitational. She stood by Ash's side as everyone argued about who was at fault in the situation. Pereira and her fellow operatives subsequently pulled them apart. After the match, Pereira was in the locker room when Ash confronted Kali and a fight broke out between them.

Unfortuately, they only managed to win due to questionable tactics by Jaimini "Kali" Shah. Led by Eliza "Ash" Cohen, their team ultimately won the tournament. Pereira later told Harry in an interview that while she was disappointed by the loss, she would definitely be returning next year to compete.Ī year later, Pereira was placed on Team Ash for the next Invitational. However, she was eliminated by Grace "Dokkaebi" Nam with a shot to the head and her team subsequently lost. Pereira and her team qualified for the final match. Following the construction of the Stadium, Harry threw the first annual Six Invitational to serve as the ultimate test for Rainbow Operators. The continued global threat of terrorism led Harry Pandey to conceive The Program. While the mission was a success, it caused tensions to rise between her and Valkyrie. This action led to Emmanuelle "Twitch" Pichon and Meghan "Valkyrie" Castellano to collaborate with Ghost Recon to conduct Operation Archangel in order to recover Pereira. Worried, Pereira went AWOL to Bolivia in order to find her brother.

In 2019, her younger brother, João "Dengoso" Pereira, was sent undercover at the Santa Blanca Drug Cartel and subsequently disappeared. Pereira formally accepted an invitation to join Rainbow in 2016. It was Pereira's role as a key interrogator during the 2010 Rio de Janeiro security crisis that caught the attention of Rainbow, despite the fact that she undermined BOPE protocol. Pereira was frequently called upon to conduct training exercises within the force. Once her mandatory service had ended, she could not see herself in another profession and reenlisted. Years of undercover operations within Brazil's notorious gangs made her a master of interrogation techniques and surveillance. Sensing protection for her deviant predisposition, Pereira accepted the latter. He gave Pereira the choice between entering a juvenile reformatory ( FEBEM) and working with the Policia Militar's BOPE as an informant. He was lenient towards her age and character, which, he claimed, showed potential for social-educational reform. Remaining poised and displaying intellect throughout the process, Pereira impressed the judge in charge of her case. A year later, Pereira was arrested miles away on robbery charges. Pereira caught the authorities' attention when she was 16 after her mother reported that she had gone missing.

At some point, Pereira was gifted her first knife by her grandmother. Pereira looked up to her grandmother and was inspired to learn about the art of interrogation. She had the uncanny ability to see through any of their lies. Their grandmother helped their often exhausted mother with discipline. Stricken by poverty, Pereira and her brothers grew to be strong and independent for the sake of their mother. She was six years old when the Pereira family was forced to move to a poor neighborhood in Rio de Janeiro. Her father had died before she was born and her mother only received a small pension for his death. Pereira was born seventh in a family of ten boys on October 15th in the small town Rinópolis within São Paulo.
