Lost - More from "Happily Ever After"

One more thing struck me about the episode that I forgot to mention in my other post, and that is Desmonds role between the two worlds. Based on the ending of the episode the sideways Desmond is aware that there are two different worlds, and his island self was also different as well. The question is if Desmond will jump between the two worlds from time to time as events go on, or will he just retain some memory of each world. Either way, he is aware of what is going on and he exists in both worlds for all of the characters, meaning he is a CONSTANT. One of the greatest episodes of Lost, if not the best one, dealt with Desmond jumping through time and he needed to find Penny in order to be his constant. A lot of people thought that the constant had to be some loved one or something like that, but as Daniel wrote in his journal, Desmond is his constant. Anyway getting to my point, the constant was a person that existed in both times that gave your mind something to latch onto in order to keep you from spinning out of control, like Desmond's driver George in the island world. With Desmond existing in both worlds and being aware of his existence and the existence of both worlds, he might be the thing that ties the two worlds together for all of the characters, in the end giving them a choice in which world they want to belong in.
