Before starting read it, this is theory post and if some of you guys thinks this is "stupidity" that's actually theory about it and I personally don't care what you thinks about

For withered jolly:

Before true identity of that Eric's corpse was revealed, many people thought this human corpse was "unknown killer" who has been trapped in suit like William afton in fnaf 3 or people also mistake or theories him as "Kevin Johnson" because they thinks he mimicking Kevin's voice and know who's Jack carson but something was wrong. A true identity was Eric Smith who's died in jolly suit until his daughter free her parents in minigame

In jolly 3 chapter 1, a blood veins are can be seen in W. Jolly's body it's unknown why the developers forgot to change it because some people will see those blood veins because it's Eric's body parts

When demo released, W. Jolly's left side of forehead seems to be missing in lcon but it changed to be back probably because ivang didn't like jolly takes more damage so they did clear

There's error/mistake. Were his leg can be seen clips through his torse (as you see it in first image just look at closer)

For Withered George:

He hasn't been charged in chapter 2 at all, only his jaw was been fixed that was only one been charged

If he's normal genius like human if he's able to understand what he do something (like how he fixed his broken jaw) but I don't even know what animatronic's iq are if they can

During jumpscare in chapter 1, were he did crawling the celling before jump to catch Jack, like mangle in fnaf 2 if he does can crawling the celling by himself or not

For Kevin Johnson:

Kevin Johnson is may not similar to William afton since he does nothing like him. What people do making theories about him that he's "similar to William afton" as both are ceo of different entertainment and gained immortality for living forever (his immortality was revealed in end of jollibee's phase 2 before taken down). Kevin is maybe villain because he hiding his true dark self and personality was revealed that he let childrens get capture and then dies. He was also revealed to be true Vengeful in jolly 4 so may he'll come back

Some people theories him as unknown person with blue suit who poisoned the foods for childrens eat it to death in jolly 1 but he's ceo and not employee just whatever people thinking about him if it was him

His last name "Johnson" was come from some Character in game called "portal" but I think ivang was fans of this game if he does know

Kevin was firstly mentioned by phone call in jolly 1 if phone guy said "kevin", "Mr. Johnson" or "The ceo"
