It wasn't because they (the o6) left....

I think Ben doesn't want Walt to come back, because he is more powerful than Locke and Ben combined, and that is the reason he let Michael leave with him, because Walt is the greatest threat of all.

In the Room 23 mobisode, Ben says that Jacob wanted Walt.  I wonder who made the decision to send him back.  Jacob?  Ben?  Bea?

Jacob wanted Locke too, but that didn't stop Ben from putting a bullet thru him.

.......... how come nothing happened when Walt and Michael left?
Is it only because Ben turned the wheel? And why is it only the Oceanic 6 who have to return, why not Walt?
Appologies if already answered.

Great question!  Why only the 06? Not even Desmond. Only those from the plane that are still alive. except for Walt.

Maybe the O6 are the ones Ben believes he can manipulate.  Des and Walt and Ji Yeon are out of his circle of influence.

Seems to me if somebody went down and turned the wheel back a couple notches, that might work too.

I'll bet it doesn't work that way.  Turning the wheel agitates the spooky Island mojo glow and once it reaches full spookitude, the magic just kicks in.  The only way of dialing in specific time/space coordinates is to build a Orchid-type microwave enclosure nearby and fiddle with dials (which are now destroyed).

ben tells richard that he comes from the future.  daniel tells ellie, i'm sure this will happen over and over.  perhaps the 6 have to go back because plans were made (who knows what!) based on having the people from the crash there.  they didn't seem surprised that the plane crashed there, they had spies and got names of who was there.  they knew so much about each passenger (and that's still a mystery of sorts, how they got that info so fast) and didn't seem all that surprised.  maybe they were waiting for the crash, based on stories handed down from the 50s, that people would come from the future, that someone would save them (from what?), that kind of thing?  so maybe they only need the 6 because they were foretold they would be there?

right, like Locke told Richard that he was the new leader in the past so they look for him and make him the new leader, so that he can tell Richard that he is the new leader in the future so they can look for him and make him the new leader in the past .... and Infinity.... . and now he is the new leader. I think this is the way it's happening. but if you ask me this seems more like a loop to me than anything. which came first? !!!! aaaaaah sometimes just when I think I'm getting it I realize I don't got it! lol
