hrmm.. wow.. that's true! in the last episode of season 3 jack not only refers to his father for the prescription which could of been his own prescription and he was just passing it off as his father.. but more disturbingly when he is talking with the black doctor in the hospital hallway.. he says "bring my father down right now and if he's drunker than I am then you can fire me". These two occurences lead to believe that he's still alive. But isn't his father supposed to be dead ??

Also.. all flashbacks throughout the seasons were always from the past.. so could this one be from the past as well ? Could kate and jack have already been on the island before? And the 3 seasons were their second trip to it ???

But that wouldn't make sense at all... yet I'm sure we are all puzzled as to how they intend to keep the next 3 seasons on the island if the end of season 3 ends in their rescue... I suspect plot holes here..
