Quote from : The Hobbit: The Desolation of Smaug Movie

Gandalf: You've changed, Bilbo Baggins. You're not the same Hobbit as the one who left the Shire...
Bilbo Baggins: I was going to tell you... I found something in the Goblin tunnels.
Gandalf: Found what? What did you find?
Bilbo Baggins: [pause]
Bilbo Baggins: My courage.
Gandalf: Good... well, that's good. You'll need it.
