Jack's Back

So yea, Jack, Kate, Hurley and Sayid are back on the island. but its 1977. last night's ep kinda sucked.

time travel sucks too.
and before you say anything, Ben can't die.
the rules wont allow it
rule #1: what happens, happens.
rule #2: if what happened doesnt happen, time will course correct.
rule #3: see rule #1.

its dumb but that's whats been established by Mrs.Hawking and Daniel Faraday. Basically, you cant change history, if you try, time will make sure it happens how it did.
it doesnt really make sense, but those are the rules we've been dealt. So, to recap, if Sayid kills kid Ben, the universe will implode into itself.
