"We shouldn't have left."

I thought the season finale was very strange and didn't answer any questions other than the fact that Naomi is probably not a good person. I am also confused about Jack and I agree with the other respondent about the comments about his father. But, also, Jack saw his father alive, once, on the island when the show first started. I was also glad to see Walt again, it means that they didn't just write off his character. At the end of the next three reasons, they better not make this a "dream" or a "hallucination". There was something not right about the "flashback" because Kate, for sure, would have been in jail unless something significant changed. I have heard of someone's sentence being commuted because of something like enduring hardship somewhere or bravery.

Lost is Lost, is Misterious. What all say go to happen the opposite exactly. Lost is surprising!

It definitely seemed to be Jack and Kate in the future. Of course, it may be like A Christmas Carol, Jack seeing the 'ghost of the future,' what life might be like if they lost-ees leave the island. I'll be curious to know who the people on the ship who sent Naomi are. Guess they'll be the next adversaries for the castaways, since the 'Others' are now fewer and in disarray.
