Jack becomes the first character to receive a second flashback as we explore how he and his father clashed professionally and the issues it caused between them. Boone and Locke also make a major discovery in the jungle. Unfortunately, for those who waited an entire month to find out what that was on the next episode, they would be let down with the worst episode of the first season and no further explanation as to what that discovery was. At least the music at the end is good? We're halfway done with Season One!
