At the beginning of The Incident, Jacob is shown wearing a white shirt and his counterpart (c'mon, we all know his name will be Esau)is wearing a black shirt. Which leads us all to believe that Jacob is the good guy and the other chap is the bad guy, which is reinforced when black shirt declares how badly he wants to kill Jacob. But the rest of their conversation is pretty ambiguous and throughout the episode Jacob doesn't do anything that is particularly nice or good. Is it possible that the two of them are simply two sides: light and dark. Not necessarily good and evil like so many people have surmised? Or will the killer twist be that the black shirt is really the good guy. These type of twists aren't unheard of on the show afterall. Thoughts?
