4x13 - "There's No Place Like Home" Part 2 Future

The flashforwards continue right from the point where "Through the Looking Glass" leaves off.

Jack and Kate

1. Jeremy Bentham? Who the hell is Jeremy Bentham and why is he dead?

2. It's confirmed that Aaron is the "he" Kate refers to when she says "he'll be wondering where I am."

Hurley and Walt

1. It's been a long time since anyone's actually seen Walt.

2. So Jeremy Bentham visited Walt. There's a scene I'd like to watch next season.

3. They're lying to protect Michael too? Does that mean he lived through the explosion?
