Some things I didn't understand - SPOILERS
So it turns out that the two lead females were behind it the whole time. It was a neat twist, but doesn't really make a lot of sense:
If one girl wants to be a famous actress, she's out of luck, now that she's a wanted serial killer.
If the other wants to be a famous director, same situation as above.
They reveal themselves as the culprits in bikinis in front of a pool, somewhere that looks expensive. How did they get $$ to run away for good? Obviously there will be a huge manhunt. There was no indication they had any money, and to hide for the rest of your lives in a tropical paradise will take some serious cash..
Any ideas? Did I miss something?
