Interesting take on Sayid. Maybe that was the only way to get into the temple was to get Sayid's body into the temple and take it over. That way he didn't have to pass the mysterious powder.
What do you think about the parallel scenarios with them on the island and landing in LAX instead of crashing?
Why is it that when they crashed the second time in Al Jeer flight 316 that Sun and Ben along with John's body stayed in the present and instead of going back to the past with the others?
