It wasn`t very major, but there are a couple of interesting thingies here.

At first we all noticed, that in fazbears mega pizzaplex there are a lot of waiter robots. So... maybe that "Moon man" was one of the waiters, who got manipulated by Vanny? Idk, but he has construction, simple to ones from this trailer.

Second- Here we see continuation, or beginning of Vanny`s talking to Gregory, while we see many other parts of Pizzaplex.

Also, Vanny`s voice slowly starts to glitch, and turn...different?

Idk, but in the end she actually sounded like Circus Baby.

What does that mean? Just a glitch effect for Vanny` s voice?

Return of Elizabeth? Or maybe... Elizabeth in Vanny?

Oh, Scott as always gave us even more questions.

Though, we just need to wait for more.
