Ethan:
I would like for Ethan to have found out that he lost another child in Eileen and be v.upset. Again losing a child being the antecedent for him being spurred back into action once more, just like how he joined Vanguard. Though this time a very different side. Ethan will probably take on an alias, though still hold on to the Wolf handle and probably just be murdering up a storm during the war. Not feeling murdered out he would probably join Wolfhound and continue murderparty there. In a vain effort to destroy everything that made him frown. However he also is with Delphine and they have a child boy. And if someone kills him god damnit…
The Brians:
Hoo boy.
Ok will start with Brian with Veronica or
Andrew Chevalier: This Brian will be with Veronica, have a baby and will be primarily fighting a lot in the war. I assume he would be a sought after asset as he could poop out a platoon or whatever to help where the fighting gets desperate. I think Vee and I need to establish more what they get up to, but being with Veronica, this Brian is definitely the more business/killin oriented Brian.
Brian Winters: Getting his name legally restored to Winters, Brian has left Fulk behind in an effort to not be the hapless boy, not be the company agent but be all that is himself. He is married to Sam by this point with little baby Ali. Also during the war he started the Lighthouse Initiative, aiding the guardians during the war and manning as many safehouses as possible Brian gathered those he could to mount rescue operations focusing on children and families in the most desperate situations. This Brian and members of the Lighthouse Initiative saw fighting and a lot of tough situations but weren't fighting to help one side or the other. They were frantically throwing themselves in harms way to pick up the broken pieces of the country that the war was making.
With the war's end, the Lighthouse Initiative would grow. All those children now in the cover of the different Lighthouse Orphanages would still be educated and some trained in combat and operations just in case the world should start to fall again. So tiny little xmen teams secretly pop up around the Lighthouse orbit. But on its face the Lighthouse Initiative is a very charitable organization that focuses on education and rehabilitation that saw some tough shit during the war. With the Safe House reopening Brian would want to come back to where it all started and put up a 'campus' (could be a couple apartments or houses, whatever) of the Lighthouse. He would be involved with the safe house council and be very cooperative with SESA. He would be running much of the organization through different bodies all over the place, but the Brian in New York will be focusing on his family and making sure New York please doesn't get fucked up anymore.
Vacation Brian: This guy has like a resort or two in Bali/The Maldives anyone who really needs a break or needs to get off grid and is trusted by Brian is sent down to his place way down in the ocean to get away. He, like Chevalier, is cut off from Brian network by choice and only checks in weekly to make sure all Brians aren't dead. He probably has a family down there.
NewGuy: Moving Brian to FC and probably going to make a lighthouse kid (around 18) for xmen lite baby adventures.
