"Exposé" had a lot of layers, and, naturally, contained plenty of Easter eggs. The Numbers made their usual appearance, and Sawyer continued to read at an impressive pace (it seems like he has a new book every time we see him). Here's what else the Lost fan community has found (spoiler warning for those who have not seen the episode):

The Numbers: There were quite a few uses of the Numbers in this week's episode. Exposé was in its fourth season, and fans are wondering if the fictional show's events hint at events to come in Lost's fourth season. Will the identity of Jacob be revealed, just as the Cobra was unmasked, in Season Four? Also, Howard's diamonds were worth eight million dollars, and the spider's poison lasts for eight hours.
