Lenny’s Sister Location theory: A power struggle between two animatronics
Maybe its just my denial talking, but I present to you this narrative: Baby never betrayed us at all, Ennard was actively working against her.
first go to where this began, Ennards origins. In Night 4 we’re told
that the suit we’re trapped inside came from Baby’s original pizzeria
and that it was never used the way it was intended. That place was the
place mentioned in the Gas Leak story.
Let me highlight a few key parts to this story
“In other news: The grand opening of Circus Baby’s Pizza World has
apparently been cancelled due to reported gas leaks in the building.
Sources close to the establishment question the report, saying that the strange activity around the area at night suggest something else is to blame.
One local is quoted as saying, "Everything just stopped. There was so
much excitement built around this place opening and then they just
stopped talking about it. There was only a handful of people
that ever got a look at the inside, kids from here and there, making
sure everything worked right, you know. I guess they weren’t quite as ready and they thought they were!”
A tenant from across the street claims to have witnessed a large group of cars surrounding the building during the night, and large pieces of equipment being taken out of the building under tarps. A few weeks later the building was for sale.”
That bolded passage in the middle is the key component here: The only
people who got to look inside are children who were acting more or less
like beta testers. Pizza World never officially opened, and yet Baby
seems to remember fondly the one and only time she got to perform..
It was after the incident with Afton’s daughter (We pretty much know its his daughter at this point) that the gas leak story
was made up and Baby and the crew were hauled off to the shipping
center to only be used privately.
Ennard was probably a side character alongside Baby. Why was he never
used? Perhaps Afton was testing out a new design of the Spring Lock
suits since Freddy Fazbears shut down. Why Ennard was never used is
unknown, but the point is The suit you’re stuck inside once belonged to Ennard
Ennard HAD to start somewhere, he had to have a base form before he
could start assimilating the other robots. So whatever character he was
in Pizza World is what he started out as. Now lets cut ahead to the time
of the game which leads to another scenario in my head: The first three nights is a power struggle between Baby and Ennard
Isn’t it weird how the thing given to employees to aid them seems to
actively want you dead? Telling you to electrocute the animatronics to
make them angry? Giving you false advice on how to get past Ballora? Telling you to ignore Baby on Night 3? Baby states she recognizes this scenario, and even KNOWS that your guide is going to lie to you.
Your Hand Unit is Ennard’s voice: He’s done this
before, killing off the technicians who come to work there, Baby’s
watched it happen before, enough to know what lies he’s going to feed
you. Then Ennard catches on that we’re being helped and some time
between Night 4 and 5 deals with Baby off-screen. Notice how much more
malicious sounding Baby is Night 4? whereas she was rather gentle to us
in the previous nights? Baby even insults you in Night 4… At that point its no longer Baby, it’s Ennard
messing with us. The Bidybabs even acknowledge the REAL Baby on Night 1, stating
that they had to leave because she was watching them. Baby is still
herself at that point.
Also we’re in the scooping room on Night 4. Baby wouldn’t be in
there, but Ennard would be to go assimilate more animatronics. Which
swings back to my theory that the suit we’re stuck in is what Ennard
used to live inside because Ennard WOULD know how to open his own face
plates. Ennards motives for not killing us right there is that he was
more or lesstrying us on for size. The suit was barely big enough to fit a person inside, if we can fit into the suit perfectly, he can fit into us perfectly.
On Night 5, Ennard has more or less taken control completely, yet has
us going through the trouble of going to see Baby’s body. Why wouldn’t
he just lead us to the scooping room right at the start? He wanted us to
find Baby for some reason. He wanted us to get rid of that card in her arm.
We take the card and then we send Baby on ahead to be scooped,
presumably so Ennard can finish assimilating her. Why would he want that
card gone though? Because perhaps Baby’s ‘good’ really is in that chip,
and if he had assimilated that her personality would conflict against
his, like having your conscious yelling at you loudly.
TL;DR: Ennard and Baby are two conflicting forces in your story, and unfortunately Ennard won.
