“A sudden understanding, a pity mixed with horror, welled up in Bilbo's heart: a glimpse of endless unmarked days without light or hope of betterment, hard stone, cold fish, sneaking and whispering. All these thoughts passed in a flash of a second. He trembled. And then quite suddenly in another flash, as if lifted by a new strength and resolve, he leaped.”

“Bilbo almost stopped breathing, and went stiff himself. He was desperate. He must get away, out of this horrible darkness, while he had any strength left. He must fight. He must stab the foul thing, put its eyes out, kill it. It meant to kill him. No, not a fair fight. He was invisible now. Gollum had no sword. Gollum had not actually threatened to kill him, or tried yet. And he was miserable, alone, lost. A sudden understanding, a pity mixed with horror, welled up in Bilbo’s heart: a glimpse of endless unmarked days without light or hope of betterment, hard stone, cold fish, sneaking and whispering.”

“Never before had I known the sudden quiver of understanding that travels from word to brain to heart, the way a new language can move, coil, swim into life under the eyes, the almost savage leap of comprehension, the instantaneous, joyful release of meaning, the way the words shed their printed bodies in a flash of heat and light.”

“Her face brightened with a sudden flash of mischief, and without warning she punched him, surprisingly hard, in the ribs. “There!” she said. “Now I feel much better.”

“If only I had thought of a Kodak! I could have flashed that glimpse of the Under-world in a second, and examined it at leisure.”

“An idea so luminous flashed across her brain that she almost thought the room had leaped into light.”
