In case 1 the polearm got discarded cause bearer must be an easterling, which it is not anymore (I told these guys to not drink anything that a small guy offers in a shinny glass... later they can't even remember what they are, and start droping things anywhere)...
In case 2: We have to check if turn into fierce = gain fierce keyword. I personally think Lurtz would lose fierce but i'm not sure. (Fierce? me? Nooooo you must be mistaken... I will just go talk with that little hobbit again cause i forgot something...)
