Interesting! I think that if we proceed with the shapeshifters: then Everett, Seth, Tank, Lady Tess (which we havent met yet) Alden and of course the no longer "Jester" we knew at first, might be at serious risk... Hell, perhaps Ruben and Dulrig as well somehow? But it seems unlikely.
In the case of Nameless however... other than the MC, I dont know who else could be affected by our decisions... Mmm.
