Once again Tactics event has dragged me here. When the paladin betrayer(Gammorin) said that the Western BoS would understand what had been done wrong if they saw MWBoS, I got this thought: If MWBoS is in the next FO, there could be an envoy from the west to "check" on their progress(because they probably heard about their success) and to learn about them, since the West suffered from isolatism and the war with NCR. I personally would like if the MWBoS ideals would be made the main BoS code(not to next FO mind you but perhaps in its end slides there could be information about BoS fate).
I kind of hope the Western BoS dies off soon.
They've left a big mark on the wasteland but it's time for them to go.
I think it'd be interesting to hear that the WBoS was overrun by the NCR but a handful of the members of the Circle of Steel managed to escape and retreat east (sneaking through Legion territory because they're assassins) and reaching the MWBoS.
