LOST Tonight (2/9) - "What Kate Does"

[Bond]

This is a good theory I came across on the alternate timelines:

"The events in the show still coincide with "whatever happened, happened". Even though the bomb went off, and the Losties went back to 2007, all the things they had accomplished still occurred (at least in this "main timeline"). This is known by the fact that when Sawyer goes back to the Dharma village everything is still wrecked ala the smoke monster when it destroyed all the people from the freightor AND the fact that the things Sawyer had burried in his house were still there. So his life with Juliet did still occur back in 1977. Daniel was wrong, the bomb didnt change anything. The true "Reset" has not occurred yet, and will be a result of what happens with the survivors who are currently at the temple and with Flock/MIB. This "true reset" is what will lead to what we are seeing as an alternate timeline back in 2004."
