Yeah he probably did do those things, I didn't pay much attention. I was (and still am) too annoyed with him that he left Eowyn to fight Nazgul by herself. I mean I really wanted to see
him kick Nazgul's ass. Show us some of that mighty wizard magic! But alas, he was too busy aiming his flash light around while buggering off the battlefield to go get some more tobacco (probably).
Also, don't take anything I say too seriously, I never read the books. And like most novel-to-film adaptations, 80% of the story is usually changed or left out of the films. Same treatment they gave my boy Harry Potter. I'm just poking fun. lol
