I've been wondering about that for years. oh well.

Good episode. I wonder what changed MIB's mind from leaving the island to destroying the island? Was that always his true intention, and leaving was just a device to get everyone on a sub together so they could blow themselves up?

One thing that bugged me: Jack consoling Sawyer. No, Sawyer, pulling the wires out of the bomb was not a good idea. Yes, Sawyer, you did kill Sayid, Sun, and Jin. You certainly didn't let Jack off the hook when Juliet died.

I loved the little breakfast scene between, Jack, his son, and Claire. It was so... quietly happy.

Good answers from Jacob, Jack's immediate response and everyone else's hesitancy has been foreshadowed, I guess. I can't really see anyone else becoming the guardian at this point anyways.

I doubt Alpert is dead.

So Ben is all out psycho again. I thought he was gonna have a decent shot at redemption, but apparently he just wants to kill, kill, kill. He's way better as a bad guy anyways.

Definitely seems like the concert will be an integral event in the sideways timeline. Should be cool.
