I was talking to my sister about fnaf mainly fnaf 4 and you know how the I will put you back together is a different yellow, Well we know William was talking to cc using the freadbear plush which we found out in fnaf 5 well William would use a voice for kids but what if when he says ‟i will put you back together‟ William drooped the act, He stopped using the voice for kids and just said it in his normal vocie...credit to my sister for the theory.
