was there anything in season 3 that touches on how Libby was in the same mental hospital as Hurley? Or a thread somewhere in here?? If Libby is "Dharma with a twist" she could be a double-spy. Perhaps she was doing some research on the Losties before they crashed, i.e. somehow got a hold of Jacob's "list" (in the future?) and was investigating who these people were exactly.
It seems they were all definitely chosen for this flight somehow, I mean, would you ever believe there were so many crazy stories and interconnections in one airplane full of people?
