One that is constantly in vicious battles, all sorts of dangerous situations? he had no experience at the helm of a ship, how could they possibly put him in the helmsman's seat, and..when did it happen?..Did I miss that one? or forget about the episode? ...or did they just all of a sudden stick him in that role one day without explaining it?
