flash sideways are the end of the show
We are already seeing the end of the show.Â The flash sideways are actually flash forwards.
I’m guessing the hero ( jack? ) defeats the MIB and time travels and/or resets the island back 20
or 30 years ( whatever ) so everyone’s life is also reset e.g. hurley is lucky, sawer is a cop, 815
never crashes and so on.
This means we wasted 6 years watching the show because with the reset none of it took place.
Maybe I’m a 100% wrong and need to reset my theory otherwise this would make the show a long con.
