As part of the side quest Honor the Fallen, Aloy must clear Snapmaws from a shrine where Rea intends to honor her fallen companion. Aloy can speak to Rea in Meridian at the start of the quest, and by the Lake Shrine after clearing out the Snapmaws. Rea explains to Aloy that she used to be a slave of the Carja. She had escaped with her companion during the Liberation of Meridian, but had lost her to machines by the lake as they ran. After clearing the Snapmaws from the area around the shrine, Rea thanks Aloy before continuing her mourning.
