So, what were the zombie-lookin' people?
Tail section survivors who have armed themselves with primitive weapons?
Tail section survivors who are now infected with the sickness?
Other "others"?List additional options. Personally, I'm thinking numero uno.

I think it's #1, and I think that if the tail section people survived that pretty much proves that something was fishy about the plane crash.

I think that one was Ana Lucia a passenger on the flight! I have a great website you should check out if you have not already:
www.oceanic-airlines.com (http://www.oceanic-airlines.com) enter in the numbers and you can check out and explore the plane. If you click on the part where the numbers and letter F are flashing you will see the plane fall apart...........
