Viewers will finally learn the truth about Jacob and the Man in Black in the May 11 episode of "Lost". In the preview, the Man in Black says to Jacob, "Do you have any idea how badly I want to kill you?"
The official synopsis from ABC is kept relatively short, saying "The true motives of John Locke are finally explained." The preview shows Smocke showing two sides - light and dark, good and evil - using Othello seeds.
According to Buddy TV, there will be a bunch of new characters as well as returning ones in the episode. The teenage boy in the jungle is back and so is the Boy in Black. The description of these two young characters lead to speculation that the Boy in Black is the younger version of the Man in Black while the boy in the jungle is actually young Jacob.
Meanwhile, Emmy-winning actress Allison Janney is guest starring as a minor role called simply as Woman. Then there's Lela Loren as Claudia and Ivo Nandi as Oldest Hunter.
