How we cite our quotes: (Chapter.Paragraph)
Quote #1
It is impossible to erase my choices. (4.34)
Tobias is living in the past early in the book, dwelling on everything from bad decisions he's made, to tattoos he's had done, to bland fashion choices he's made. (Gray shirt, blue jeans, black shoes? Try some color, dude.) By the end of the book, he learns to live for the present, not the past, and that helps him get over some of his regrets.
Quote #2
"My parents would want me to save [Caleb] though." [Tris's] eyes open and lift to the sky. "They would say it's selfish to let someone die just because they wronged you." (9.14)
Even though Caleb betrayed Tris, she knows that she would feel guilty if she just let him die. Breaking him out of jail is a preemptive strike against future guilt. This way, she won't have to regret making a bad choice.
Quote #3
I don't know. I don't feel anything. My hands go numb, so I know I'm panicking, but I don't really feel it, not the way I normally do. (20.46)
Tobias kind of feels guilt for not feeling guilt that his father is going to be executed… if that makes sense. He's feeling a societal pressure that he should care about his dad, just because he's his dad. But Tobias can't muster up any sympathy for the man who abused him for the majority of his life.
