Although last week’s episode didn’t contain as much excitement and intrigue as “The Substitute”, there were still plenty of great moments to keep viewers interested. The episode focused a great deal on Jack and his personality differences in the two universes. Off the island, we found that this version of Jack had a son and that the relationship with him was very similar to the one Jack had with his own father. Jack’s son doesn’t respond to him well nor does he seem all to excited to spend time with him as Jack struggles to find a connection. At the end of the episode Jack manages to establish a positive connection with his son by explaining that he’ll be proud of him no matter what, something Jack’s father seem to never tell him.

Back on the island, Jacob instructs Hurley to lead Jack  to a mysterious lighthouse that they never had seen before. During the journey we get to see the old school trek that we became so use to witnessing duringthe first season, especially when Jack and Hurley come across the caves where most of the passengers stayed early on in the series. This was the most interesting storyline of this episode because it appeared that we were approaching some answers to some of the mysteries involving Jacob and his selection of specific people on the island. Although there weren’t really answers provided, there was a new mystery introduced: the lighthouse has a mirror that can see specific points off the island. When the coordinates of the light house are turned to a specific number that corresponds to one of the characters, the mirror reflects a piece f their lives. Jack struggles with this concept because he feels like Jacob is taking his free will and he destroys the mirror. Oddly, Jacob doesn’t seem too upset with the destruction and has other plans in store.

Claire re-emergence played a background role in this episode. She is basically insane and seems convinced that the “others” took Aaron form her. Jin notices she’s a little off and lies to Claire and tells her that Kate doesn’t have the baby….smart move. Claire returning to the temple with Jin can spell danger for the remaining inhabitants.

Overall the episode was pretty good, there weren’t too many new developments and it kind of seems like we’re being set up for somehting big in the upcoming episodes. There is still much to be figured out, especially when it comes to the sides of good and evil in the battle between Jacob and the Man in Black.
