Came here looking for answers too.
Im assuming its a very common? Bug.
I think I might have managed to kill him once with all the barrels and not trigger the whole camp going hostile. but that
in itself might be a bug.
Glad to see Im not the only person who managed to 'one shot' the whole of that room. I threw a potato at the hinge
holding the brazier to detonate. Its ultimate cheese though imho. I heard him banging on about drinking from
barrels and got 'inspiration'. but who in their right mind would let somebody place barrels everywhere and not say anything?
Oh wait. I thinkn I just answered that last question lol
