Continuity mistake: When Sidney is first going into the house for the end of the movie it is clear that she is not wearing the vest underneath her clothes and as she is walking around or when she is rolling on the ground fighting with her half brother you see her bellybutton but then she has the vest on and it goes over the belly button.

Question: Is there any significance to the code '1288' Sydney uses at her mountain hideaway?





Answer: Not expressly, though it could have been the date of some significant event (December of 1988) but someone as security-conscious as Sydney now is wouldn't be stupid enough to have her code be something that could be guessed.
