Elizabeth Afton is a minor character and was the daughter of William Afton and the sister of Michael and the late Evan Afton, who trusted her father and held a deep fascination with his creations, especially Circus Baby, until the machine captured and killed her, which allowed Elizabeth to possess it...is what happens in the original timeline, but that's not what we're doing here. On top of being innocent and somewhat of a lonely child, Elizabeth has a ragingly obvious British accent.
