Okay, for those of you out there who watch LOST...... what the heck!!!! Do you think that's real?, Does Jack really end up like that?, Who was in the casket?, Why would he want to go back?, Why didn't Charlie swim out the hole?, Who was Naomi?!!!!! What the freak is going on?! Someone help me and answer some questions... how am I supposed to wait until September?!
