Trilogy Theories.

[Patrice Maire]

Here's an even scarier thought....
Remember Quaritch's quote about a Marine in a Na'vi body? And Lang's comment about 'not as long as i have DNA'?

::shudders::
Quaritch as a Na'vi.

I still don't think that's in the scenario for the sequels. I can see Grace coming back, we never saw them bury her. What if she comes back as some 'Obi Wan Kenobi' type ghost for Jake to learn from?
Offshore drilling for what? You can't easily mine under water so there's got to be some other hook. How about the pollution from the mine has affected the oceans... the Ikran clans report a huge rise in dead animals on the beaches...

So many possibilities out there, we can speculate all we want and maybe even come close to what he has in his head but it will still be a surprise when it is announced.
