Quote 61
He hits the water with force and the sea is filled with rocks here. There's no telling how deep or shallow it is. He could seriously die doing this. He could—but he pops up, shaking the water off his short yellow hair and whooping. (54.31)
If you were already dead and could do anything you wanted, what would you do? Jump off cliffs? Dive out of airplanes without a parachute? Hang out with poisonous snakes? (Wait, scratch that last one—it's not even fun to imagine.)
Quote 62
I had killed those dogs. It was I who lived with dogs, I who knew where Prince Philip and Fatima slept. The rest of the Liars didn't think about the goldens—not very much, anyway. Not like I did. (75.76)
The Liars become a unit when they're together, and it's hard to tell their personalities apart. This is the one glimpse Cadence gives us of a separate inner life—prior to her accident, anyway. After the accident, she's not just separate, but alone.
Quote 63
I wanted so much for us: a life free of constriction and prejudice. A life free to love and be loved.
And here, I have killed them. (82.12-13)
Realizing the world will never conform to your ideals is one of the harshest realities of growing up. Coming to this realization because you accidentally murdered three people you adore takes it to a whole other level.
