Jaacob tells charlie hes a werewolf in breaking dawn.
Jacob Ephraim Black is what Stephanie Meyer gave him. He is named after his great grandfather Ephraim Black who was the last werewolf pack leader.
Jacob is a werewolf. Technically, he does not become a werewolf until the second novel, New Moon, and he remains a werewolf for the rest of the series.
He said that because JAcob Black was coming, and Jacob is a werewolf, enemy of the vampire ;)
