on syfy they aired season 4 opener last night. it got me thinking. charlie must be alive. he was seen by the other mental patient, only thing that doesnt make sense is he disappears when hurley counts to five. i think jacob saved charlie. i believe we will be taken back to the scene where charlie dies and after desmond rushes away jacob comes out of one of the closets and breaks the glass window on the door to release the water. jacob will perform cpr and revive charlie. this is what charlie meant when he said he did die.
