If anyone watched the end of Lost last night, you may realise that Hurley inferred that he didn't want to see any of the other survivors from the island.
How could a guy so lovable not want to see his mates? What's up with that?
Maybe he felt so trumatised by the events on the island that he didn't want to see that same group of people together again as it could bring back terrible memories or maybe he felt that others were still after the survivors for stumbling across the island and therefore discovering a civilisation which, should of remained secret all that time.
I hope this all makes sense!
