She is an incredibly loyal Disassembly Drone who, as a regular Worker Drone in her youth, was repurposed and befriended by Tessa to serve at Elliott Manor as a maid, where she met N, Vand the AbsoluteSolver disguised as Cyn. J assisted Tessa on the night they tried to prevent the Solver from slaughtering a gala at the mansion, though their efforts were in vain as J was among all the Worker servants who were corrupted by the malevolent AI to help with its murderous plan.
