What makes you say Penny is on the way ?
How is Juliet getting off the island by lyingto Jack and working WITH Ben ?
Why wouldn't Jack take all the survivors back to the camp that the others left?
This is the bit that brought a tear to my eye
Penny "Why didn't you write?"
Desmond "How did you find me?"
Penny
"I have a lot of money Desmond........ with enough money and determination you can find anyone".
You also see more related to this statement in the end of season 2. She has posted trackers in the artic looking for Desmond. Ever since he went missing on the around the world trip. And they found him!!!!!!!!
She is on her way.
I can't wait for them to be re-united
Man, your second one is harder and unless your the writer, no one can answer that one for you. Ben know's what he is doing. He is smart. He wouldn't let Locke just blow up his only way on and off this island, it's just stupid. He knew what Locke was up too, and just willingly let him go and blow it up. I think not mate, there is another way to get on and off this island. A back up sub? Who know's, but Ben know's that there is another way.
Your third question.
Don't forget, there is 3 fluffy black clouds on the island, and treaking through a jungle isn't smart.
Secondly, you forget about that sonic fence they have all around the place. They are better off where they are.
Help will come......
Though, the others will be back before that happens I think........
1 week!!!
