Oh,another character I'd like to see a flashback of:Libby! She says she's a shrink,she was in the same psych ward as Hurley yet she also gave Desmond the boat to get to the island! Is she involved with Dhrma?

Also,in the Mobisode featuring Hurley,there is a guy named Neil aka Frogurt. Well,I was watching an season 2 episode and he is mentioned in it too! Bernard asks for him when making that GIANT SOS sign in the sand. The producers have confirmed that Frogurt will be in season 4!
