The end of your argument is kind of like saying nobody would know river dale if they didn’t copy Heathers in that one episode, that doesn’t mean making it not toxic makes it right, they are siblings, Elizabeth is in circus baby and the fun times fused together to form Ennard, and if you don’t believe me search up the search code from this one teaser, the source code reads
Your crowding us
We outnumber you, you can’t tell us what we’re doing anymore
Yes I can
Be quiet, yes I do, you will do everything I say
We’ve found a way to eject you
Say goodbye to our friend~
I will put myself back together
That was the source code, it basically proves Baby was apart of Ennard with all the other fun times but was kicked out, thus, why she’s a separate entity in fnaf sim, but people ship the Ennard who is from sister location and still has Elizabeth’s soul inside. I did my research, does it hurt I’m saying my opinion?
