The building mystery of "why they were all on the same plane" would be interesting if we didn't learn the answer to that question 5.5 years ago.
Though I would like to know what's in the box that Christian left for Claire.
It was also nice to see MIB's charade with the Losties finally come to a close. That's been a long time in coming.
AND THE KWON's ARE DEAD... aren't they?
And why didn't MIB melt in the water? I thought he was the wicked witch of the west or something.
