I agree with it being after TSL, but not the rest. How does Carth and Bastila show up on board the ship if the Exile didn't notice them on board earlier? And why would Jolee and Juhani be there? But I do sort of like the idea of fleeing the Mass Shadow Generator, but if it was in the game, it should be the opening scene. No gameplay necessary.
Yesterday is history. Tomorrow, a mystery. Today is a gift...that is why it is called the present.
