Hi, please please don't comment on this thread if you've allready seen the future episodes, but, how awesome was tonights episode!
This is my theory so far

Ethane is the french womans son, who crashed on the island 16 years ago.
The physcic man told Clare to get on the plane knowing it would crash and she'd be safe, however, there is another form of "being" on earth, evil beings who are after her baby, and they're on the island, Ethane is working for them.(Maybe the Devil/Aliens)

Everyone on the island is chosen to be there for wrong doings in Life, it's a Bermuda trianglr thing?


I think?
