After she went on a shopping trip, and the Team Flare announcement was made while Lexi was in Anistar City, Brigette myseriously disappeared. It was later revealed that she was actually Lysandre's daughter and Trevor's sister, who had asked her to keep close to Lexi in order to ensure she didn't get too close to their plans. Brigette revealed she didn't want to do it but in order to protect her brother she had no other choice.
Despite her connection to Lysandre, she eventually turned against him in order to take him down. After the event, Brigette went back to Hoenn.
