He died at some point in my game and I didn't notice it until much later, so I couldn't even load an earlier save.
He doesn't say anything about it, as if that was not a big deal. Now he follows me as a spirit. Well, if it's not a problem for him... it's not a problem for me.
It seems that in the current state of the game you would have to bend over backwards to keep him alive, so I really can't be bothered.
