LOST Revisited: 6-7 “Dr. Linus”
This is our first mention of the Island or Dharma in Timeline X, which is significant in and of itself. But both of them were on the Island in 1977 when the bomb (supposedly) went off. You could make a case that Benry was evacuated with the women and children, but Roger was definitely on the Island. This would seem to indicate pretty definitively that Timeline X was not created by the detonation of Jughead. And it gets even better when there’s a knock at the door, and it’s Alex Rousseau! Awesome!
