Revealing mistake: When Abby and Jen are drinking on the dock, Abby suddenly falls into the ocean and drowns. Just as they show a close-up of Abby falling about to hit the water, you can tell it's a stunt person. Monica Keena is a fairly short actress, and the stunt person is noticably taller with longer legs. Also, Abby had been wearing a very decorated black and silver skirt while on the dock. But the person about to hit the water appears to be wearing dark clothing without any silver or glitter.
