mental hospital:
the scene where the T1000 becomes, then reconstitutes from the floor.
floor is checkerboard.
EVERY other scene of that hospital shows white, NO checkerboard.
i never noticed before. gave my wife chills showing it to her.
edit: i remember it was a checkerboard floor, i just never noticed that that was the ONLY mental hospital scene that showed the floor as checkerboard.
Unless you are way up in the club, you can only guess.
Black and white floors are just one sign that you may be looking at something cabal related.
Someone with black and white checkered floors in their mansion that shakes hands funny is probably cabal.
Guesses: duality, balance. Do evil, but offset with good deeds.
