First off,remember Sands'(Johnny Depp)fake arm?Well,at the end of the movie,after Sands' eyeballs have been sucked out and he's lying outside on the ground and his girlfriend,Aljuerez(Eva Mendes)comes over to him she says,"You f***ing little monkey,".Now notice as she says that and he's lying on the ground,he does not have the fake arm.He never did during this period of time.Well,she lifts him up and she's up to him,getting ready to shoot him.

You here a gunshot,and to her surprise,his fake arm underneathe,was secretly up against her and he shot her!But notice,where the hell did the fake arm and gun from?
