Wow, it's been a while since I've last seen this thread! The whole visions of DS Exile and Revan could mean (based of the LSF choice) that in K3, the Exile will be faced with a choice - fall to the Dark Side and stand by Revan, who's been tainted by the True Sith, or stay in the Light Side and fight him. Right when he's on his deathbed expecting a final blow, the Exile encourages Revan to return to the Light Side, for his sake, for the Republic's sake, and for Bastila's sake. 'course you could always give him that final blow and call it a day
