The dead person.. They made it seem like it would be Michael…but I doubt it..clues were too obvious. Whoever it was, Kate showed disdain for. It would then have to be someone she cared enough about.. Sawyer. Sawyer has clearly reached an inflecton point in his life. Killing “Sawyer” triggered it…and he definitely showed signs of distancing himself from her…that baby comment was just a killer. You know..a woman scorned. Sawyer also had no friends. Locke would also never leave the island. We’ll see.
The future look. I just thought that was an awesome move by the writers. I definitely want to know what happens to several of these folks once they have to face the realities of the people and circumstances they left behind.  Not to mention the impact of living on the island..the surreal, detached experience had to change them. I agree with another poster..the ‘father’ comment was just him being really unhinged. Matthew Fox really did an incredible job in that episode..he really looked tortured.ÂÂ
Charley is dead.  Catch the baby start to cry at the moment he died? But I’d like to know how that one-eyed jack is so indestructible.ÂÂ
Not Penny’s Boat. I hope Desmond got the message.
Why didn’t Locke kill Jack? because he’s not a killer? Uh…then wasn’t it he who killed the new girl from the helicopter/boat?ÂÂ
What a great series. ÂÂ
Sawyer was my first thought, and Jack’s conversation with Kate at the end made me think that even more, but I’m still leaning towards John.
Nobody saw who threw the knife that killed Naomi. We are lead to believe it was Locke, however Locke cannot kill. Locke did however teach Walt how to throw Knives!!! Locke has a tendency to use others to kill for him.
