Partridge isn't so sure—to be in a cage or set loose into this world? This is a question that he should be able to answer. Does some part of him wish he were back in the Dome? (26.40)
You know, Partridge sacrificed a whole lot to escape the Dome. He had a pretty sweet lifestyle in the Dome: he had a pretty date to the dance, sanitation, and a nice roommate. Going outside the Dome was a pretty big risk.
"If you want to find your mother, you will need our help. The matter is whether or not you're willing to sacrifice for your goal." (37.66)
Would you give up a pinky to find your lost mother? Partridge would.
"I was," he says again. "And now I'm not." (46.36)
It's interesting to think about Sedge as a human in this book: he suffers just as much as other characters. Especially because he had to sacrifice his human life to be a special forces creature.
"He wouldn't know if we were alive, but he was willing to sacrifice that knowledge to make us think that he'd died." (53.17)
Not knowing is sometimes better than knowing. Sacrificing knowledge can be pretty dangerous, but for Ellery, pretending to be dead is better than knowing if others were alive.
"It was the story of a child who was cared for—a child with a routine. A healthy child. A child better off where she was." (53.43)
One of the biggest sacrifices of them all; Aribelle leaves Pressia with her grandfather because she had a better chance of surviving with him.
"I made a small sacrifice," he said. "Do you want to take it back?" He stares at the bandage, the end darkened by dry blood. He shakes his head. "No." (54.26)
Partridge's pinky sacrifice is difficult to begin with, but he refuses the offer to have it fixed? Missing a pinky is now a part of him; sometimes sacrifices can make you who you are.
"Tell your father that he can have whatever he wants. He can have the pills. He can take me. Just not this." (56.17)
Nothing can trump the safety of your child. Aribelle is willing to give up her whole mission just for the safety of Sedge.
She raises the gun, takes aim at her mother, draws in a breath, lets it halfway out, and then she closes her eyes. She pulls the trigger. (57.10)
Pressia isn't exactly sacrificing her mother here, because she's going to die anyway. But by shooting her, Pressia is giving up a part of herself: her childhood.
"I never activated the ticker. I switched the wiring. If anyone flipped the switch, it would only deactivate the bugs. I said I wouldn't put you in harm's way. I promised." (59.67)
Ingership's wife could have conformed to his rules. If she had followed his orders, she would have been safe. But she still puts her own life in danger for the sake of the wretches.
Lyda is about to ask him what will happen to them now [...] "I'm here now." There is no returning. (59.107)
Like Partridge, Lyda also has to sacrifice her own life inside the Dome. But really, do you think she had a choice?
