i just hope they dont do a whole time loop storyline where they never get back to 2007 and are stuck in the 70s and 1 of them becomes jacob and 2 of them become adam and eve and the rest do whatever they want (die in the purge maybe) and then it shows the plan crashing again in 2004 so its just an inevitable time loop, thatd be a cop out if you ask me... although im pretty convinced that jacob, adam and eve all must be characters we already know so its quite likely something like that will happen

they need to escape the 70s, go back to 2007 and get involved in a war between ben and widmore
