Maybe poor Fen perished in the battle, mainly because I can't find a muse to play him anymore.

Isam could be alive and well, perhaps more at peace with himself now that he's had several years between himself and the migration. 

Omar would a NCP still.

And Sasha could have healed up and integrated into the group. I had an idea for him having been a soldier for the Neo-Nazis back when he was young and gullible, and then he came to his senses as he got older and saw what pieces of shit he was working for. Having had past experience on the battlefield, and being the large man that he was, he could very easily fit the "tank" character type :3
