In regards to Jack's dad I recall 2 instances of him being mentioned. I one Jack's comments were loaded with sarcasm, and in the other The chemist was going to call Jacks father and He hung the phone up on her. - he also made excuses for her not to. Both those times he was pretty fucked up.
So is the future set in stone? or will we see different possible outcomes?
I guess the main question now is 'Will Desmond get the word to Hurley/Jack in time that the boat people are not who we thought they are?'
I guess it'd be a waste of Charlie's heroism if he doesn't.
I didn't quite understand why Charlie sealed himself in either. Maybe to preserve the outcome Des saw - Des made a big deal about events having changed when he saved Charlie form a fatal arrow to the throat. I mean, Surely they'd have had enough time to leave station - even without scuba gear, they'd be able to swim up faster than they swam down. Maybe I've missed something?
Anyone else notice how different Walt looked? The actors voice had even broken since he was a cast regular.
