If you own the DVD go to <0:14:00>: It's the scene when Ronna is at the cops house (she doesn't know they're cops) just the moment when Adam and Zack talk to her and detective Burke is getting her a bottle Cerveza out the kitchen. After he brought and gave her the bottle, they talk a little and then during strange behaviour Ronna suddenly realizes that something must be wrong with those guys and that she's supposely trapped (actually the guys try to pull her into a trap)! Her first thought is to get rid of those exstacy pills she carries with her. She askes for the bathroom and pretending to want to show her the way to it Zack walks straight at her and she passes him on the LEFT! Keep that in mind, cuz this is the point when the mistake happens! She passes him on the LEFT!!! And then directly jump to <1:07:12>: Same scene shot from different angles and a couple dialogue lines from before are varied and abridged, but therefore others were added instead. Watch again the moment when Zack walks straight on to Ronna to show her the bathroom. This time you see him giving her a secretly whispered hint that she should "GO!", to let her know it's an entrapment. And then watch them closely! This time, at the repetition of the scene from before, you see Ronna passing Zack on the RIGHT! It's hard to recognize, but it's true! It was NOT intended or caused by changing angles! This is irrevocably, without any doubt a real and hard-to-find slip-up! Everyone can check it for himself. This is the mistake I meant and which no one else recognized before, cuz it's extremely hard to even realize! :)
