What if the flash sideways is how it all turns out, but it is kind of
like the "deals" being rewarded to the losties, that thy are making w/
MIB and/or Jacob.
So Jacob & MIB promise people things to persuade them to carry out
their agendas, BUT the people don't get them until they are in the
alternate timeline.
We have seen that both Jacob & MIB promise people things.
Sayid.... wants Nadia to be alive,
Claire ...wants her baby
Sawyer....to be off the island (or possibly have juliet again)
Maybe Jacks will be something about being a good father.
I dunno it's hard to say at this point b/c we haven't seen everyone
interact w/ Jacob or MIB at this point and we haven't seen everyone's
flash sideways yet.
But also contrary to this theory is that Dogan has already make a deal
w/ Jacob concerning his son being alive again but Dogan can not see/be
with him.
There are plenty of holes or variables in this one, but it was just a
thought.
