Bilbo slumped down against the wall, his heart racing from his escape from that foul creature and its obscure riddles. He turned his head at a distant rattle of rocks, though he couldn't see a thing. The darkness was almost painful in these blasted caves. He felt it closing in around him, pressing down on him, threatening to bury him here under this mountain.
He put his hand in his pocket and touched the ring, and was astonished when he got a sudden burst of will, something that pushed the oppressive darkness away. He would get out of these caves.
