Soon he learns that there is a fight between the Man in Black, who believes that mankind is evil, and Jacob, who believes that mankind is good. Jacon offers immortality to Ricardo to work for him. But the Man in Black tells that his offer is still open.
"Ab Aeterno", which means "from eternity" in Latin, is the best episode of this confused Six Season and one of the best of "Lost" ever. The dramatic and supernatural story of Ricardo, a.k.a. Ricardo, is engaging and with top-notch performances. The relationship between the Man in Black and Jacob is explained a little further. My vote is nine.
Title (Brazil): "Ab Aeterno"
