I wonder what will happen with Walt anyway. It seems so odd that he seemed like such an important player in the early part of the show and now he still hasn't shown up for his turn of melodrama. Maybe in the last episode. Who knows.

I agree that they're killing off all the most interesting characters. It's just annoying. But then, with everyone so interested in knowing what will happen, I suppose we were always going to be set up for disappointment in a big way. Too much buildup for a show to be able to fulfill, I think.

EDIT: Of course, the fact that they're all 'alive' in the alternate reality world thing makes me suspect that pretty much every death is just another farcical event that didn't actually happen. The deaths almost mean nothing. Which is kind of annoying. At least we still have Hurley and Desmond...
