Frodo died. Gollum had something to do with it, and Frodo was now decidedly dead. Aragorn had a great love for Frodo, but no amiable feeling of affection for the ring, so it fell to him to destroy it. He walked for years across a huge field of tall, yellow, dead grass, all alone. He went for so long without eating anything, but he had some immortal blood in him, so he wasn't starving. Suddenly, out of nowhere, a ghastly forest appeared, and Aragorn was starting to get lost and bewildered. His strength began to visibly seep from his body; his life was fading. He stumbled, and couldn't even stop his fall.
Then, huge bears, about ten feet tall, came out of the trees. Their claws were almost as long as Aragorn's arm, and they surrounded him, and were about to eat him, when Aslan appeared next to Aragorn with a bunch of little dwarves. "Take him to Narnia," Aslan commanded. "They'll never find him there."
