TW: some mentions of death
Missing nightguards:
I feel like this route could make sense? as Madison's was never made as an actual franchise for kids, Mr Harper wanted it to be this way but Mrs Andra was making it a trap, especially for nightguards and the kills are indirect(aka caused by animatronics mostly Madison)
Andra's motives:
Mrs Andra didn't want to pay for nightguards cause she was already paying the bakers and mechanics, so when she hires nightguards, after their 5-10 night shifts she just sets a trap for them to die
Mr Harper being unaware:

he is aware, he warned that he will break off the partnership but when Rachel got hired as an nightguard he was on vacation
Max having photo proof and reports of animatronics being hostile:
He started to get them when nightguard 5# started to work.

Will there be an custom night/night 9:
...Maybe, maybe not.
Will there be easter eggs:
maybe about other fnaf fangames/fnaf content creators. I am not completely sure
