Ethan is a clue
I found the revelation of the baby being Ethan a bit weird. Why would the writers show us the whole storyline of Amy being pregnant and having a baby and then show us that the baby’s name is Ethan. Ethan has never played a big role. Until now I think.
I still believe that the past can be changed by the losties but Ethan I think is sort of a clue that the past can NOT be changed.
If Sawyer and Juliet would not have saved Amy, Ethan would probably not have been born.
That means that Sawyer and Juliet saving Amy, was ‘part of the plan’; it was supposed to happen.
And that would mean that what is happening now, has already happened before the 815 crash.
Ok, this might be a little far-fetched. But the writers didn’t show us the Amy-Ethan thing for nothing. I’m starting to believe that the past can not be changed, and that what’s happening now, has already happened pre-815.
