There are questions that the characters should have asked. So you think that Jacob magically transmitted his centuries of knowledge and experience to Jack with the magic stream water? Hmmm.

Jacob didn't get his mother's knowledge when he drank the enchanted wine and she told him that now he is like her. Obviously he did not or he wouldn't have pushed his brother into the light. Jacob was dim even after he became the caretaker. A couple thousand years later and he seems to know quite a lot.

Jacob made a world-screwing-up mistake shortly after becoming the caretaker. How many people have died because he didn't know how it all worked? But he has no concern that Jack needs to know anything.

I think you put way more thought into this than they do, michel. I think there are two reasons that information doesn't get shared in a natural way on the show. One is that they haven't thought it all out (the writers), but the fans take care of that as you do by thinking out for them. Two is that they're holding on to mystery.

I don't expect to ever know how a smoke monster exists and functions at this point. They made it clear they were leaving pseudo-science behind when they went for magic light in the cave as the reason for everything.

So now they slay the dragon for the Finale. It's all been very simplistic for a show that pretended to be extremely complex. It's all coming down to let's kill the bad guy before he kills us.

I don't agree that questions can't be asked as it goes along. This episode was part of the Finale (according to Darlton, they consider it like all one episode, same as with other finales.) They have two and a half hours left, including commercials, and there is no reason to thing they'll come back and answer any of the questions I just asked.

My questions are simply about why characters do what they do. I stop believing in (suspending my disbelief) characters that aren't written to behave sensibly. I've never seen a movie or TV show where the characters got handed a mission this big and inexplicable. Jeez, the person with all the answers is disappearing forever. At least ask Jacob how to kill he who cannot be killed with bullets or mortar rounds.
