Apologies for not getting this up earlier. In episode 002, we pick up with Richard Alpert in 'Ab Aeterno' (Sorry if the clips from 'Ab Aeterno' look a little more pixelated than the rest of the episode, it didn't encode as well as I would have liked). In between his time in prison and crashing on the island, we see Jacob's conversation with the Man in Black before the Black Rock arrives. The episode concludes with another time flash, when everyone flashed to 1954, with Locke reuniting with Sawyer, Juliet & Co.
