everyone is coming back

so i am a little behind in the episodes and i am trying to catch back up. the episode i just watched was about the oceanic 6 getting back to the island. it was an interesting episode that had a lot going on. it started off by showing us more scenes from the plane ride where they come back to the island. i am confused how the pilot knows everyone and i am curious to see what he and sun will have to go to find the others. the reason why no one saw the plane crash on the island is because it happened in present time, whereas they were looking in the past. the show is starting to get very confusing. the pilot and sun end up meeting christian sheppard who is jack's dad and he says he will tell them how to get to gin and their friends and that it will be a long journey. i am very interested to see how they will go back in time, but knowing this show they will find a way to make it happen. also, jack kate and hurley are all living in the barracks with dharma initiative and were assigned jobs. as for sayid, he was captured as a hostile an they do not know what to do with him yet. it was interesting to see sayid meet ben as a child although i am not sure if he realized that is what happened. i think that jack realized that sawyer and juliet are now together and jack does not know what to do with himself now that he is not in charge. the next episode should be interesting and i am sure they will make the next few episodes about how sun and the pilot will travel back in time..but i wonder what will happen with ben?
