When Audrey is editing together the video for Rachael she is using Apple's Final Cut Pro X software, which only works on Mac OS X; but the laptop she's editing on is not an Apple computer, and wouldn't be able to run the software.
All of the characters incorrectly claim Rachael's body was found hanging from the ceiling fan in her room, when we can clearly see it was hung from a light fixture in some kind of sitting room. The color of the walls, furniture, window/door placement and hanging location do not match with her room at all.
