Why do we never see his mother, in fact how would Elizabeth have orange hair 

Not all characters need to be on screen

Her mom's hair could be orange

Oh please

We have every single afton character BUT Mrs afton , why is somebody who never appeared again ( evan) more important than the wife of a killer

Because his role was clearly more significant than william's wife's role

Evans only role far as we see is him dying

That's all he is usually known for

No pictures of a wife , no hint of a wife - for fucks shakes no wife in fnsf 4 to look after her kids

Like thst has to mean something

Because his death was the downhill trend for Fazbear entertainment.

And that's my point. If he murders 6 children, why would he adopt one and care for it

"Care" if he had a wife let's not forget he left his bully of a son alone an we KNOW his been killing before Charlie

Or at least planned to do it before Charlie

If anything he used them for remnant

Like in the book (not Canon ) he slaps his daughter for nothing

"Care" if he had a wife let's not forget he left his bully of a son alone an we KNOW his been killing before Charlie 

The mci caused freddy's to shut down btw

Circus baby.

We know his been making them pretty fredbears we also know Charlie was alive during that time

Im sorry, but say what you will about william, but he DID on some fundamental level care about his Children. He wouldn't have bought the toys they cherish, or decent rooms if so. And elizabeth wouldn't have been nearly as spoiled if William cared not at all.

He specifically told Elizabeth to stay clear from circus baby which shows some level of love as a parent.
