If you're not confused, maybe you could explain how Desmond's consciousness jumping works, and why sometimes '04 Desmond takes over '96 Desmond, and sometimes it's vice versa. And if '96 Desmond "jumped in" on the helicopter, taking over for the rest of the episode, how come he told Penny on the phone that he had been on an island, as if he suddenly remembered? Why does his physical body pass out sometimes when his consciousness jumps to a different time, yet others, he stays awake and regains his memory of where he is and who he is with? And if he jumped to the future to see all of Charlie's deaths, why did he get deja vu when he relived those moments? Wouldn't his past consciousness jump in and take over in those moments, leaving him totally bewildered? There are too many paradoxes, unless I'm way off on everything. Please share ideas.
