My first idea is Jenny gets a new sister Xj10 to help with crime fighting and other stuff like house care.
Nora has to leave for a while and Jenny is left in charge but XJ-10 gets jealous and wants to be in charge so she manages to use code from XJ-1 and XJ- 3 to effect Jenny causing her to act more babyish spiting up oil and needing diapers and be clumsy so XJ-10 can takes over.
And maybe she takes Jenny some places with just robots so no one will help her like Cluster Prime or somewhere.
My 2nd idea is similar Jenny is with XJ-1 who's sick of baby treatment and the bugs she has and hated how Jenny talks down to her and finds away to swap codes with her causing Jenny to start acting like a baby and XJ-1 starts acting like a Teen and gets a new body.
We can discuss more details in these I'd like to be Jenny anyone interested in being one of the other XJs?
I also have these ideas if your interested
