What you May Have Missed

• Ben and Ethan hunted down Rousseau, before the Purge. This means that, like Ben, Ethan defected from his DHARMA family before everyone was killed.
• Widmore was banished while the Others were living in the Barracks, this puts his exile some time after the Purge in December 1992.
• Widmore tells Ben he's been looking for the Island for almost 20 years. Given that his banishment in what was probably early 1993 and the Ajira 316 in early 2008, it's only been 15 years since he's been off the Island.
  
• Desmond and Penny's boat is named after the Charles Dickens book Desmond vowed not to read until he was about to die, Our Mutual Friend.
• The container with the guns that was on Ajira 316 had AA823 written on the side, two of the Numbers.
• When Ilana asked Lapidus this question, it made no sense, so we should look at the context clues. She and others opened a container on the plane that had guns. She claimed to work for the family of one of Widmore's associates. The question might relate to the four-toed statue on the Island looming over the Temple. Put the pieces together, and this question was a code for Widmore's secret agents to identify one another.
• The "main" hieroglyphic in the Temple basement was of the Egyptian god Anubis bowing before the Black Smoke Monster. In Egyption mythology, Anubis was brothers with Horus. Horus is believed to be the four toed statue. But what's in his shadow?
• When Smokey judged Ben, one of the scenes with him and Alex showed her telling him that she hates him. This may not have been a familiar scene for the casual fans, because that dialogue was from a deleted scene from "I Do" after Ben hooks Karl up to the God Loves You As He Loves Jacob brainwashing machine.
