It hasn't been built yet. The fifth season of one of the best TV series is back. The first two episodes of LOST were broadcasted on Wednesday and they were amazing, mainly the first one. When Ben moved the island in the last episode of the fourth season, I kept wondering what has happened to the people on it and well, now we know. They are continuously tortured by time jumps similar to a music from a broken record, as my favourite character Daniel Faraday said. During one of these jumps, Daniel talks to his constant, Desmond Hume, who is still in charge of the Hatch!
Daniel tells him to go to Oxford to see his mother. In the LOST universe, she may as well be Ms. Hawking, who was seen in the second part talking to Ben and giving him 70 hours to fix the mess.
