I have BEEN reviewing very carefully EVERY episode of LOST!! My findings from MY brain power have led me TO vincent!! AS i suspect he is AN evil little PUPPY!! HE led Sharon to her death and HE gave druggy Charlie even more DRUGS for FREE!! He also was THERE when charlie put SUN in a bag to keep HER dry when he dragged her INTO the jungle!! Vincent DID not tell anyone about Charlie and HE did not even try to help!! He ALSO knew that the RAFT was going to blow up as REFUSED to go on it!!
