Quote 19
I took the pen out of his hand—he always read with a pen—and wrote Gat on the back of his left, and Cadence on the back of his right. (5.39)
That's a pretty bold move, and ridiculously romantic. Our hearts are pounding for her. (Also, we've been practicing writing on both our hands—We Were Liars could spawn an ambidextrous generation.)
Quote 20
But we were only fourteen. I had never kissed a boy, though I would kiss a few the next school year, and somehow we didn't label it love. (5.42)
Aha… So Cadence does kiss other boys; it's just that none are Gat. First kisses have a way of branding your brain and your heart, and making subsequent kisses pale in comparison.
Quote 21
It was love, and it hit me so hard I leaned against the screen door that still stood between us, just to stay vertical. I wanted to touch him like he was a bunny, a kitten, something so special and soft your fingertips can't leave it alone. The universe was good because he was in it. (6.17)
When Cadence sees how beautiful the Gat Universe is, the Sinclair Universe starts to look ugly in comparison. Sometimes seeing the good casts a bright light on the bad.
