I was waiting painfully to see what is the end.......Some explanation as to what happened ..... Was it just a mass delusion as Ben says......was it a sneak peak into future , as Ben says : we have 3 kids , Cal will be cured .....but the flight comes back with 11 not there ..... 4 LONG seasons with NO logical explanation as to what the whole series is about.....just divine consciuosness ???
