I’m really excited about what’s coming up on the first few episodes of Lost this season. We’re supposed to see what’s in the hatch over the first three episodes and we also get to see what the other group of survivors have been up to (the ones from the back of the plane).
We are also supposed to see what happened to the plane itself and why it went down before the end of season 2. There was speculation that there would be a mini-movie about this on the DVD set of season 1, but apparently that might not have been done.
All of this is purely rumored and speculated.
I even heard that one of the aliens in the hatch is going to take control of the body of one of the main characters.
