My two penn'th ....
Remember that the Vishnans said that humanity should be preserved because they build communities out of warring factions ? The first storyline was about a 'hero' of the GTVA doing the right thing, the second storyline when complete will be about Laporte 'doing the right thing' and probably refusing to do something to the GTVA which would drive a wedge between humanity factions and the Vasudans, and the third part will be when the GTVA, the Vasudans and the UEF all come together as the Vishnans predicted, to kick the Shivans good and proper.
Its so similar to Bablylon 5 in many ways with the Shadows, the Vorlons and the First Ones, with the Humanity/Vasudan pairing similar to the Human/Minbari thread.
Just my views - it may have been said in the previous 200 pages but I must admit I have not checked.
