Gandalf : Sauron has yet to release his deadliest servant. The one who will lead Mordor's armies in war. The one they say no living Man can kill. The Witch-king of Angmar. You've met him before. He stabbed Frodo on Weathertop. He is the lord of the Nazgûl, the greatest of the Nine.
Pippin: What, the puss Strider sent screaming with an improvised torch?
On an almost entirely unrelated movie set,
after Frodo's unpleasant stay at Chateau de Cirith Ungol, where he received a most unhobbity haircut,
as Frodo's eyes glaze over in rapt focus on his precious boom pole, Sam encourages him to share the load.
