I've finished Season 3 of LOST and I wanna talk about it. (open spoilers)

I think it had to be ambigious, otherwise it would be a total giveaway… Theres loads of references to things we don’t understand inside the episode. Lots of people saying Jack was famous for something, but not saying what… So while you might be pitying him for something different…

If it was just that, then perhaps, but:

“JACK: That’s not me, that’s Doctor Christian Shephard, I’m Doctor Jack Shephard, he’s my father.”

Its present tense… He would have said “he was his father”. Its explainable by saying that he’s pretending his father is alive in order to prescribe himself drugs… However, two of them?

Exile!

That’s an interesting idea.
