OK i killed him again, Boone just says that intel indicated "They have a whole line of succession planned out", doesn't mention who. Says Caesars death won't stop them, might not even slow them down, they'll just replace him with whoever's next in line. Also says he wasn't really in control of the army any more.
But Vulpes must have thought of this... after all Caesar is obviously very ill.
Anyway, yeah why not self-fill if no one else does, I'll pretend to be your OP and cheer you on xD
