in one of the endings. we see that in custom night ( fnac remastered )

if we turn everyones level to 0. we waste our power then we get an secret ending.

after we hit 6am. we get a pink slip. mary was fired for "tampering with the animatronics."

we see a shadow of the rat.

seemingly mary was fired and is now long gone, so..

did mary survive?

seemingly in the fnac2 minigames. we see a dead security guard. and that is mary.

but what if WE ( human in real life ) save mary by tampering with the animatronics and firing mary.

is she still alive?

is emil up to something seemingly to "pretend" that mary's story is over?

that's just my theory.

full context

Mary is dead. ( by how we play the game ) Mary is alive aswell ( by how we play the game. )

mary can't forget about the "purple cat" because the purple cat is watching her forever.

mary WANTS to fully "kill" or "forget" about the purple cat b going to the rowboatics corp facility. ( fnac 4 ) seemingly to end her suffering from the tormentation of the purple cat.
