I know we probably shouldn't be talking about this but I can't help myself! DO NOT READ IF YOU HAVE NOT SEEN THE FINALE
Here's one of my several questions: Why didn't anyone think it was weird that there was a blinding white light? Everyone acted like nothing happened afterward! Also, I was reading the message boards and someone borught up that maybe Libby's husband David is Hurleys imaginary friend "Dave". Also Penny's dad must be part of Hanso. Penny is defintily looking for Desmond. And on the Lost forums, someone said that maybe Libby was hired by Windmore to meet Desmond and give him the boat so he would enter the race and end up at the island. But I'm not sure about that. I think she ended up in the mental institution b/c she went crazy after her husband's death.
