We already knew there would be flashforwards after the Jack thing at the end of last season. Unless you mean all of his flashbacks, and in which case, not so. First of all, he won the lottery in his flashbacks and got the numbers from that guy in the mental institution, and yet he mentions winning the lottery whilst on the island. Secondly, pretty sure we saw Libby in one of the mental institution flashbacks. And she's sorta, y'know, dead.
Everyone can freakin' see dead people in Lost. Jack seeing his dad, Locke seeing Boone, etc. etc. Nothing new at all!We also get the new information that, er, he can see dead people.
I hope Naomi is actually dead. I don't know what it is about her, but something just rubs me up the wrong way.
