Venus buys 3 bottles of red wine from a liquor store. Getting home, she gulps down vodka, maybe 3 finger widths straight from the bottle. Soon the same bottle is shown with just a modest sip taken.

When it shows Brian's wife in the bathtub after her death, the water isn't nearly dark enough for her to have bled to death. It was barely tinted pink, but if she had exsanguinated, it would have been a dark red, practically black.

shutter opening and closing, still Brian, presses quickly the shutter-release button multiple times, instead of one steady press.
