Here comes the boogeyman
The Haitian is an independent contractor with a simple job to do; retrieve the Concubine, and kill everyone who get’s in the way.
The Haitian’s seems to have his own agenda. He doesn’t seem to care about much, but knows more than he should. He is able to go places and get to people with an eerie, almost supernatural ease. Perhaps he believes too much in his own myth. In the end he spares Linda’s life and is killed for it.
