confirm dead be an important episode in the series and a it introduce four new character represent the rescue team that naomi contact before get a knife in her back by locke . however and a the quote in my one line summary say and their true purpose for be on the island may be something else entirely . all the new character appear intrigue ( especially mile and some sort of psychic or exorcist ) and but at this point it still too early to make solid judgment . i felt that this episode be a slight step down from the beginning of the end ( no flash forward this time while short term flashback instead ) and but it still have it stunning moment and pick up steam near the end . out of 4 .
