The Fellowship of the Ring
Even Gollum was not wholly ruined. He had proved tougher than even one of the Wise would have guessed – as a Hobbit might. There was a little corner of his mind that was still his own, and light came through it, as through a chink in the dark: light out of the past, it was actually pleasant, I think, to hear a kindly voice again, bringing up such memories of wind, and trees, and sun on the grass, and such forgotten things. (1.2.107)
Pity? It was Pity that stayed [Bilbo's] hand. Pity, and Mercy: not to strike without need. And he has been well rewarded, Frodo. Be sure that he took so little hurt from the evil, and escaped in the end, because he began his ownership of the Ring so. With Pity. (1.2.145)
"Just this, my dear old Frodo: you are miserable, because you don't know how to say good-bye. You meant to leave the Shire, of course. But danger has come on you sooner than you expected, and now you are making up your mind to go at once. And you don't want to. We are very sorry for you."
Frodo opened his mouth and shut it again. His look of surprise was so comical that they laughed. "Dear old Frodo!" said Pippin. "Did you really think you had thrown dust in all our eyes?" (1.5.51-2)
