Continuity mistake: Chilling on the couch watching a movie, Jay's friend farts. Obviously well practiced in the discipline, it takes her merely moments within the same shot to perform the necessary adjustments after the emission and place her index finger back on the dainty seashell lid of her media device. But in the next shot, as she proudly smiles basking in the warm glow of her successful feat, her finger is off the lid. (00:07:00)
Continuity mistake: When Hugh turns around to take a look at the audience and spot Jay's pick, in the faraway shot his whole arm goes over the seat, hand with the soda included. The scene continues with the Hugh's drink always next to the popcorn as he is turned to different°. (00:10:30)
Continuity mistake: Jay is soaking in the pool. She drowns a bug that is on her arm. Behind her there's a can of soft drink with a straw sticking out and pointing towards the left. It stays that way until she floats on her back and there's a semi-POV shot with her toes sticking out. After that, the straw in the cola can is pointing towards the right for the rest of the scene. (00:05:00)
Continuity mistake: When Hugh brings Jay to the edge of the parking lot to show her "it", the naked woman "it" is shaped as is wearing flipflops, which she does not wear when she slowly walks on the platform. Quite the funny little off-camera wardrobe adjustment to make for a zombie-like supernatural entity on a path of death and destruction. (00:20:20)
Answer: The scene was meant to show that Jay was seriously considering having sex with a stranger and passing the curse on, as she was told to do. At the last minute she changed her mind, presumably due to guilt.
