How we cite our quotes: (Paragraph)
Quote #1
"What was right with him he'd only give you a little at a time. What was wrong with him he kept bottled up inside." (20)
Right out of the gate, we learn that Andy keeps secrets, and that this trait has lead to some pretty heavy consequences in his life. This helps establish his character, and sets us up for some surprising developments yet to come.
Quote #2
"He looked up at Bogs, smiling that little smile of his, old Ernie said, as if the three of them had been discussing stocks and bonds with him instead of throwing it to him just as hard as they could." (99)
Red mentions Andy's smile a lot. It's a smile that hides things, a smile that says "I know something you don't know." The whole book might just be an effort to find out what makes Andy smile the way he does—something so good that even prison can't wipe it off his face.
Quote #3
"Bogs was found in his cell, badly beaten, one morning in early June, when he didn't show up in the breakfast nose-count. He wouldn't say who had done it, or how they had gotten to him." (103)
An important part of every secret is trusting that whatever it is, it'll stay secret. We never find out who dropped the Hammer on Bogs. Red voices suspicions, but he leaves it there: Just another secret for all of us to ponder.
