it could have been that the guy who had lipstick smeared on him was setup by a guy at a party he was drinking with. The guy gets drunk, his friends mess with him... pure perfume on him and smear lipstick on him. Now he is guilty in the eyes of his wife while being only innocent of being stupid.
yeah... that's sounds pretty good. use that one on your wife.
All you NOT GUILTY make my head hurt. You will go half way around the world to figure out how Amber did it, but ignore the fact the Scott admitted to being the last person to see her alive, and admitted to being in the same spot where her body was dumped. You completely and conveniently forget to mention the whole part about how he told Amber that "he lost his wife, and this would be the first holiday season without her."
Poor, poor scott. He is the most unlucky person in the whole world. He predicts that his wife will not spend Christmas with him, and then some unnamed evildoers kidnaps Lacy, then finds out where Scott was, then dumps her body, days after Scott has been cavorting with Francois and Pasquale.
I could go on, but it would just be wasted.
