(BATDR SPOILERS) So, in BATDR, it has been revealed that not only could Joey not have kids, but he also had Audrey as his daughter. I thought that I could make Audrey HENRY'S daughter instead because he didn't have any kids before the events of BATIM, but I thought it over recently and came up with a new idea. Audrey was left behind by her parents, making sense how she didn't know Joey was her dad, correct? I thought that maybe, after the incident when Sala and Bill were four, Joey had made the prototypes for a better daughter to throw out Sala and take Audrey instead. This didn't go to plan, and Joey had to throw out the final Audrey as his wife (Susie Campbell) found out what her husband was doing. The reason why Audrey was an adult was that she was created as an eight-year-old to replace Sala at the time, but it malfunctioned. After being thrown out she suddenly aged up due to her body still being a bit... new I suppose. Since we do not know Audrey's age currently, I will make her 19 (the American age makes her an adult). Do the math yourself lmao, Sala's twelve now, so how old was Audrey? I'm not going to spoil anything else! Have a good day!
CFAU by me lol
