A thought I had about...who is Devlin Stone?
In the Prime universe, did the Arthur Steiner-Davion hypothesis ever pan out? Because if it's true...
...then in the EA-verse, Devlin Stone is really Arthur Whitman-Steiner, fourth child of Melissa Steiner and Richard "Big Daddy" Whitman.
If he is, then how to explain how he ended up as commanding general of the TSDF?
He was a prodigy at tactics and strategy, but even worse at politics than his now-deceased older brother, Victor Richard Jr. I would posit that, too far removed from the Lyran succession, he opted to join, or was directed to, the special forces and eventually secret service, LIC or Loki. He was given a mission unlike any other: become one of our deepest-cover agents. Change your face and your name, disavow all your Lyran royal heritage, and become a virtual nobody. Then you will infiltrate the Terran Supremacy and do your best to rise as high as you can in their command structure, secretly and subtly working to change, undermine, and erode the TSDF from within. (For the good of the Commonwealth, of course.) And he succeeded far beyond expectations, going as far as TSDF commanding general.
So yes, there's my take on who EA-Devlin Stone is and how he got there.
cheers,
